Possible Fixes

No, and I tried it on the newest version and it did not happen so thanks for fixing it

Modpack Version

2.1.0

What happened?

I opened the Tetra workbench and hit the scroll wheel button, that caused maybe half my items to disappear, I then broke the bench trying to get them back and they were deleted.

I was able to do it again, it seems that if you just take the item out of the bench you get them all back, so they are only deleted if you stupidly broke the block.
