About time... I only have 4 backpack spaces with so many things being linked. I cannot send them to my bank mini...
BTW the mailbox, when full, accepts new messages and pushes the old out of view.
All four of my minifigs (including the ones that literally have never left Avant Gardens or gotten a faction -- they serve only to hold my overflow items) have mailboxes that are overflowing with mail. I was initially nervous that I might lose the old, unviewable messages somehow if my mailbox got too full, but I quickly got over those feelings once it become obvious that I'd either have to send my extra items somewhere or quit playing the game entirely until a bank came out. Right now, I'm guessing that each minifig's mailbox probably has close to 50 items.
This might be a problem considering that the vault can only store up to 240 items (and most of my minifigs can't even get to Nexus Tower at this point because they're factionless), but once we know what old achievement/mission items are available to buy back at Nexus Tower, I'll delete those items from my active 'figs.
Really can't wait for this -- at last I'll be able to link all those random drop items that I've been waiting for months to try out!
I really wish there was a way to unlink items if they turned out to be not what we wanted. IN Beta, you could sell them to the vendor & buy them back to unlink, at no real cost, and then give or mail them away.
