Wait... what? I've only been able to place 8. What am I doing wrong?
18 pieces of storage, period. That includes the Insp and Enh storage, so if you have a bunch of those, then that takes away from what you have for Salvage. Also, there Used to be a per room limit, but I don't think that's still in effect.
Somewhere else it was written that they can't increase the limit and have the bases not crash. Something about the amount of items a base can hold as a whole. With that logic, us asking for more of Anything in the base seems problematic.
