Game Crashes with exception about feudaltactics HOT 7 CLOSED

I just observed it as well. I will try to re-do the UI change in a different way and see if the crash still happens.

Thanks for reporting! This seems to be a bug in libGDX. I recently added the buttons that give you control over the enemy turn speed and the ability to skip it. Maybe the manipulation of the UI can cause this crash if it happens while rendering is in progress. It might also be caused by the changing texture of the speed button. Do you remember if you pressed that button when the crash happened?

Interesting! Thanks for the quick response. I don't recall changing the speed, but I can't rule it out 100% sadly. I will observe it more closely if the crash happens again.

I observed it again, same callstack after Your Turn console log. This time I am sure I only clicked the end turn button. The crash happened immediately after clicking the "end turn" button, the moves of the enemy were not executed (or at least not displayed, even though I have set it to 300ms).

Possibly an additional related bug: I think restoring from the saved game allowed me to skip the enemy turn.

When the exception happens, only the UI thread crashes. The bots still do their turns and when they are done, an autosave happens. It would be better if all threads ended in case of an exception. Not sure if there is an easy way to do this.

Ok, if just the animation is missing, but everything is saved and resumed correctly then it is not a big issue to me, especially if it only happens in case of an exception which usually will be rare. Thanks for the investigation!

Changing from one set of buttons to the other was triggered by a change of the game state which was triggered by the bot AI thread. It looks like the UI classes from libGDX are not thread-safe. When the button change happened at the same time as the rendering thread tried to render the UI, this exception (and possibly others) could occur.
If something similar happens again, please re-open.
