Devs increase slots and each slot/stack 99->999, but there nothing about bulkhere : " The number of slots in a bag is now 500 and 1000 in a player's apartment."
Bigger bag bulk so it does work
Atm in players appartament 250 slots (2000 bulk). Increasing to 1000, solve identical items (not)stacking problem, but in current situation, most players running faster out of bulk, not of slots (maybe except GH, if store not full stacks and/or crafted/looted items)
If devs "just" increase 99->999 without adding bulk, and fix stacking - this not solve current storage problem
