ERR panic: runtime error: slice bounds out of range [:-1] about seanime HOT 2 CLOSED

I was able to reproduce it. The issue comes from the hydrator trying to find sequels when it detects episode numbers that are higher than the max on AniList. I assumed it would always find at least one sequel before trying to remap the episodes and that's where it crashed.
Here's what you can do:

• For All Purpose Cultural Cat Girl Nuku Nuku, rename Ep13 and Ep14 to SP01 and SP02.
• Not sure about Starship Girl Yamamoto Yohko since I don't have the full list of files but I assume it's the same issue because I see that it has one special on AniDB.

Alright so, for Starship Girl Yamamoto Yohko it seems like the matcher got it confused with the OVA, that basically shares the same name but only has 3 episodes so the same issue happened (not totally sure, i'll do some additional tests).
The crash should be avoided by adding "(1999)" to each filename for now.
