The main reason i was wondering is, as a crafter i ended up with 8 mules to hold all my crystals. And i go through em'
Some of them have been completely full. safe, sack, satchel, inventory etc. Allowing clusters to stack is going to save me an incredible amount of room. And if that one synth above was added... i would save an unbelievable amount of room. 12 stacks of crystals converted into one space.. would love it' lol
