When u try to sort the colossal chest it spams the last part of this:
[15:41:08] [main/ERROR]: InvTweaks: [ERROR] [3] Failed to sort container: null
java.lang.ArrayIndexOutOfBoundsException: null
[15:41:08] [main/INFO]: [CHAT] InvTweaks: [ERROR] [3] Failed to sort container: null
[15:41:08] [main/INFO]: [invtweaks.InvTweaks:handleMiddleClick:744]: java.lang.ArrayIndexOutOfBoundsException
-[15:41:08] [main/WARN]: Indexed inventory at inconsistent with last empty 3374 and last non-empty 3374.-

Working in latest versions. The buttons overlap the colossal chest UI in some gui scales but the sorting works
