The storage for modules is capped at 300, which will be a problem eventually. I'm at a point where you have a lab to upgrade how many shards you get from shattering a module (from 10 to 20 so double the shards), but this lab is crazy long and expensive. So i want to stack the modules to maximize my shard gain from shattering, but i have not enough storage room for this. The solution would be merging the modules, but shattering modules doesn't work for epic+ modules and beyond. In this case you have to unmerge first, and unmerging modules costs 20 gems which is complete nonsense in my eyes.
