1) Allow overfilling the vault without preventing you from putting items in, but charge a daily 'over the limit' fee. If you want, you could even scale the fee up as the overage increases.


2)Remove bulk as a vault limitation and change it strictly to an item count limit. Since the database stores each stack item as one entry, allowing us to have a 9999 stack of bricks does not increase the database load.


Either of these options would appeal to many who complain about the tiny vault space.
