Description of the issue:

I was attempting to use the Crusher to crush the ores into their respective dusts. However, the crusher would stop processing items after it had processed 4. If I let it stop and then threw in more ores, it would process 4 of the newly thrown in ores, but would ignore the ones already in there until I climbed in to grab them and threw them back in.

Crashlog:

The game is not crashing.
