I was building a design in a single-player creative world, and had brought it to a single-player survival world to use a schematic cannon to build it. After finishing up the factory and powering everything, I was very quickly thrown off by a crash to the desktop.

I read through the crash log quickly to find that there was a ticking block entity error. I changed removeErroringTileEntities to true in forge-server.toml config so I could enter the world and see if I could remove the broken block. Replacing the mechanical crafter by hand had seemed to fix the bug in the end.

I did some other experimentation by changing the length of the belt leading to the crafter, but no matter what, if a mechanical crafter was placed on a belt by a schematic cannon, and fed by an andesite funnel; it would cause a crash.

I will attach a picture of the design I used to test the bug out, as well as the relevant crash log

I just discovered a similar bug with the mechanical crafter placed by a Schematicannon.

This was fixed in Create 0.3.2g, closing.
