Got a crash the moment I tried using a CraftingTweaks button in a vanilla crafting table to spread items across the grid:

It suspects that either the Presents mod or IGCM caused the crash. Not sure what's happening though.

Have you reported it to the presents mod as well?

I believe I did on their page. With all the recent versions, the issue hasn't come back. I will close this and will inform the proper people if it comes up again. Thanks.
