I think I found another one with Corporea: It look like the crystal cube can't read more than one stack from a storage drawer now (the display maxes out at 64). It still works normally with a regular chest though.

I rolled back to 0.6.3 for a minute to double check and it looks like it was displaying the correct number there.

Botania.r1.8-unofficial-0.6.4.2.jar
StorageDrawers-1.8.9-2.4.4.jar (checked against 2.4.2 as well)
