[2.0.30] Crash RecipeTree::canCraftNumberOfTimes

[blargh2015]

This crash has happened to me twice tonight with the same looking stack trace. Attaching both logs.

Thanks for the report. Do you have any way to reproduce this? From the crash, it seems to be when hovering the mouse over some recipe widget somewhere or when having the crafting GUI open and some items in your inventory change.

Both times I did have the crafting menu open and was mousing over things. I'll try more to see if I can figure out what else is needed to cause it./
