At this Line it says "50% brown, 50% any other color"
https://github.com/GTNewHorizons/twilightforest/blob/master/src/main/java/twilightforest/entity/passive/EntityTFBighorn.java#L28

But here it says random next int 15 instead of 16, resulting in a boundary Error.
https://github.com/GTNewHorizons/twilightforest/blob/master/src/main/java/twilightforest/entity/passive/EntityTFBighorn.java#L37

This will result in Black Bighorns never existing unless you bring inc sacs from the Overworld, because Squids require a specific Water Height that is not a given in Twilight Forest, except for the TODO in the Urghast Tower claiming there is supposed to be a Squid Tank.

If the comment was also to be believed technically the chance of random to turn out 12 too, would slightly weigh it even more towards brown Bighorns. But I guess that is not really important. ;)

issue related to : GTMEGA/EndlessIDs#143

When I tried to launch with it I've got:

cpw.mods.fml.common.LoaderException: java.lang.NoClassDefFoundError: twilightforest/biomes/TFBiomeBase at cpw.mods.fml.common.LoadController.transition(LoadController.java:163) at cpw.mods.fml.common.Loader.preinitializeMods(Loader.java:559) at cpw.mods.fml.client.FMLClientHandler.beginMinecraftLoading(FMLClientHandler.java:243) at net.minecraft.client.Minecraft.func_71384_a(Minecraft.java:480) at net.minecraft.client.Minecraft.func_99999_d(Minecraft.java:878) at net.minecraft.client.main.Main.main(SourceFile:148) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) at net.minecraft.launchwrapper.Launch.main(Launch.java:28)

Is there some dependencies or it's just hardly built-in to GTNH Modpack?

Exception in server tick loop

Was exploring twilight forest and encountered this crash. Looks unrelated to #71 at first glance. Could be a GT problem?

java.lang.IllegalArgumentException: Tile entity of type gregtech.common.blocks.GT_TileEntity_Ores (jar:file:/home/Minecraft/mods/gregtech-5.09.45.168.jar!/gregtech/common/blocks/GT_TileEntity_Ores.class) reports coordinates of (-576, 28, 2063) that lie outside of the bounds of chunk (x=-44, z=134) in dimension 7 - ending up with illegal in-chunk coordinates of (128, 28, -81).

Killed a Naga and got a Hydra Trophy, using TwilightForest-2.6.20-pre

Bonus:

TF logs dont have a name ^
they do when they drop tho:

Should probably add it as a required dependency?

A client-side class is being loaded server-side here:

Namely net.minecraft.client.Minecraft.

@Gordon-Frohman The refactor you submitted is breaking automation.

From my community:

Not an incredibly common thing to do with these items(though a neat lighting/alarm alternative), but I am concerned this may branch into other larger problems. I am not sure what other changes were made to the item besides aspects, but the Block Placer places the "out of date" ones just fine, and can't place the new ones.
Cicada (working, but out of date) item id: 1816
Cicada (not working, current) item id: 8651:1
Firefly (working, but out of date) item id: 1815
Firefly (not working, current) item id: 8657

Also are IDs being occupied needlessly with the new refactor?

Your Expectation

The Reality

Edit: this compat is now disabled in GTNH which resolves some of these issues but not others, which are still relevant for use outside of GTNH:

(resolved)
this is clearly caused by this strange nuggetknightmetel oredict

(unresolved)

Also:

(unresolved)

(unresolved)

there is also duplicate ticon materials for things like knightmetal. (resolved)

And there are nugget->ingot and ingot->nugget crafting grid recipes. (resolved)

And ticon fluids and recycling where sofar we have been using a gt fluid and gt recycling. (resolved)

Your Proposal

remove the oredict

If you use [Skinport Unofficial] (https://github.com/RetroForge/SkinPort) ，Giants will not display skins correctly.

Just a List of minor things I noticed during my time of adding Compat to Twilight Forest:

• Naga Scales are not increased when using Looting Weapons, all other Bosses do drop more with Looting (except Urghast, but that one is a Chest)

• Helmetcrabs when on Fire still drop Raw Fish instead of Cooked Fish. (GT6 happens to fix that lack of roasting the Fish)

• Filled Maps (Magic Map / Maze Map / Ore Map) still stack to a size of 1 instead of 64, which is a holdover from older MC Versions that did not allow Map duplication. Vanilla Filled Maps do stack to 64 in 1.7.10. (GT6 happens to increase that max stacksize too)

• Crumble Horn, Peacock Fan, Ore Magnet and the Giant Pickaxe have an insanely low max durability by two orders of magnitude too little (yeah about two decimal digits too little), which makes them almost single use to the point of nobody actually wanting to use them, because you dont get much from them breaking near instantly. (GT6 sets their durability to 10000 for all four of those)

Too bad Mending does not exist yet, because then it would actually make sense that you need to recharge them with EXP Orbs.

I fixed most of these Issues in GT6, so it will work with the old Twilight Forest Versions too, but I wanted to mention it just so there is a record of the Issues I noticed. ^^

Random crash in worldgen on exploring TF, very close to the world portal. First instance of triggering this simply kicks the player. If they re-login, it crashes the entire server.

GTNH 2.6.1

Seems similar to #71

    // also suck up mini ghasts
    List<EntityTFMiniGhast> ghastsBelow = worldObj.getEntitiesWithinAABB(EntityTFMiniGhast.class, below);

Change the
player.attackEntityFrom(DamageSource.anvil, 3);

to
player.attackEntityFrom(DamageSource.generic, 3);

this causes damage to player but does not break the helmets if does not have durability

Twilight Forest somehow uses Block Metadata 49 for the Biome Dirt and Biome Grass layer.

I got a report for a weird crash and noticed that a Block ID/Metadata extender caused Twilight Forests Biome Dirt and Biome Grass Layer in all of its Biomes to have MetaData 49.

Without the Block ID/Metadata Extender installed, it will turn into MetaData 1 thanks to a &15 sanity check, which is ALSO incorrect, as that makes Twilight Forests Dirt into Coarse Dirt, and Twilight Forests Grass into... Grass with an invalid Metadata value.

This might need some investigation or a simple Ctrl+F for the number 49 to replace it with a 0 inside some Biome related superclass in Twilight Forest.

I suspect it was just a mishap when trying to port the mod from the ID system to the "newer" block registry system in 1.7.10.

While searching for how much extra Damage the Axe does when charging I found that the +3.5 Hearts of extra damage are never applied to anything because the following function is never called.

And instead the private variable is used to calculate Damage

https://github.com/GTNewHorizons/twilightforest/blob/master/src/main/java/twilightforest/item/ItemTFMinotaurAxe.java#L117-L119

And yes I tested that in world too. No Extra Damage at all.

Edit: Same applies to Knightly Weapons just that THOSE have their Code for the +1 Heart of Damage commented out entirely.
