Modpack version:
2.3.1

Description:
The immersive engineering crusher will ignore (void) any ores dropped into it if it is currently processing a different stone variant of the same ore.

Steps to reproduce:

1. Obtain a IE crusher
2. Drop a certain number of ore (E.G iron) into it from a specific stone time (E.G. gabbro).
3. While it is processing the first ore, drop ore of identical type (E.G. Iron) but different stone variant (E.G. shale)
4. While the first (gabbro) ore will be processed, any amount of the new variant (shale) will not be processed.
   Expected behavior:
   The crusher is supposed to grind up both ores.

Underground Biomes Ores drop the regular Ore variants without Silk Touch, so hopefully this won't come up a lot.
