Describe the bug
I was testing the ammo production in a creative world. Sending a bullet core (by conveyor) to the ammunition workshop made the world unusable due to crashing. The workshop had a casing filled with gunpowder already when the core was added.

To Reproduce
Steps to reproduce the behavior:

1. Assemble ammunition workshop
2. Add filled casing (by any method)
3. Add lead revolver core ( by any method)
4. Crash

Expected behavior
The core and casing would be assembled into a bullet
