Issue description

Game and mod were working fine and could use menu multiple times without issue and then I pressed the button to open the menu like normal but the game lagged, opened saving world and then crashed with it saying Caused by: java.util.ConcurrentModificationException. Once this crash happens the menu cannot be opened again without it crashing rendering the mod unsuable.

Steps to reproduce

Open Menu with keybind.

It's probably an error caused by a mod called "l2tabs" since it modifies some internal minecraft code. In case the mod's author needs to know the exact error: The ConcurrentModifcationException is caused by TabInventory.java#44
