Issue Detail

This crash occurs when using both MoreCreativeTabs and Supplementaries. The game crashes while Forge is in its loading stage, but adding a creative tab resource pack after the game has fully loaded doesn't cause any issues. This crash only seems to occur when creative tabs are actually customized using MoreCreativeTabs. Without a resource pack, the game does NOT crash with both mods present.

i need that pock then. by that crash i can only see some impossible conditions like objects not being registered which can never be the case. i would report that to that mod

Here's an example of a pack that crashes the game when loaded
