Place any amount of blocks in crafting station, then right clicking on it to removes 1/2 of it and crashes.
Tried on vanilla crafting table and no issue, no crashing.

Full crash log here.

Using: Forge 28.1.79
craftingstation-2.1.1.jar

Reported to Mouse tweaks as well, although it only crashes using your mods crafting table and not vanilla crafting table nor other mods crafting tables. Link to the report here.

Hope it helps to get debugged. Thanks.

The bug is in corails pillar, not my mod, report to them

Thanks for the suggestion.
I have reported to them as you suggest.

It only seems to happen on your crafting table when using Mouse tweaks.

report for Corail is here.

Hmm, not my fault other people write unsafe recipes. I will not be changing it as a recipe should never be asking about slots outside of the crafting inventory as it's a bug, it does not matter that vanilla hides the issue, it's still a bug and it should be fixed on their side.
