Version: 2.1.1

Actually, in general anything stored in the internal inventory of the "Arcane Crafting Terminal" does not drop on breaking. Breakage source does not matter (tested with a pickaxe, tested with a ae2 wrench).

Sorry for the delay, should be fixed in the next update.

Please let me know if the issue is fixed.
