I was bored when i ws KO'd so tested something out, it appears you are able to go to your gang vault whilst in the yard and withdraw some items, and no they do not go to your backpack for all you sneaky people who were about to do this, not sure if this is intended or not but just shouting it out there 

Not intended but not really major either, just doesn't have the "no can view!!!" flag on the pages.

I'll correct it Monday. Until then, have fun perusing the vault from the yard?
