Issue description:
Crashed when trying to take out tiny dry rubber from LPU from industrial foregoing with a crafting station.
If crashed, link to crash report (use a site such as pastebin):

Versions: TConstruct-1.16.5-3.0.3.126 / industrial-foregoing-1.16.5-3.2.11-55cb112.

• Minecraft: 1.16.5
• Forge: forge-36-1.2
• Mantle: Mantle-1.16.5-1.6.92
• Tinkers Construct: TConstruct-1.16.5-3.0.3.126

Confirm below that this issue is not covered on the roadmap or "Whats New?"
As far as im aware no.
Can it be reproduced with just Tinkers Construct? If not, list the other mods required to reproduce the issue.
No it would need Industrial Foregoing.

The crash report makes no sense as its getting an array out of bounds error in a context that lacks any array accesses. I assume a mixin or a coremod is to blame.

Do what the issue template recommended and reproduce with minimal mods. Give me a crash report with less than 10 mods, ideally less than 5. You may need to try a few combinations to find the proper mod list.

It really does happen with only TCon and IF - it looks like the mixins were obscuring part of the stack trace, the array out of bounds error happens inside ArrayList.

Here's a clean crash report

Looks like an industrial foregoing issue. They are doing something really weird with inventories. Report this issue to them so we can figure it out.

Further investigation: dragging items in and out normally works fine [EDIT: there's actually a constant logspam background noise of "failed client tasks" even when doing nothing], only shift-click crashes. Though I think I managed to dupe an item by putting an incorrect item in the bucket input slot [first slot], I can't reproduce it reliably. Trying to drop any item [including tiny dry rubber] into the output slots crashes with a similar error.
