Update the mod. This issue has been fixed for a long time

Sure?
The log file says that the error comes from the library mod. However, I don't have this library in my modpack. But I have the Fruits Delight mod in the modpack and the library, if I saw it correctly, is integrated into this mod. Therefore I don't know how to update the library because fruits delight uses the last version of l2library that was integrated into the mod.

Ah, I forgot to update it in Fruits Delight workspace. I will update it in next version. Anyway you should be able to fix it by installing L2Library separately. Your installation will take precedence over the the builtin library
