Last time I played I accidently sent my entire game to the bank. I had a Remote Bank Access but I cannot find it. I've been to city bank and not there. So - stupid question of the day - what happened to my Bank Access?
I've accidentally lost my banking device a couple of times by unknowingly placed it within a container, try methodically going through all of yours. Also if you have any alts/friends with lot access double check their banks too in case the device was moved last by one of them before you sent the lot to the bank, I've done that also. I rarely check my alt's banks so didn't noticed for the longest time when I thought I'd nuked an item.
I heard that if you put the bank device into the bank, then open it while talking to a banker, it opens a portal and allows the Guardian to return. True story!
@Aldornia the item name is "Remote Bank Access Device". If you don't find it in your bank, PM me and I can help you look for it when I get off work.
I am very bad at losing my portable banks, I just seem to leave them everywhere, and I will also put them in the wrong bags, thinking they are lost for months, and yet, I was carrying them around the whole time. I think its one of my super powers.
Make use of your Decoration Palette, which is accessed via the Window Selector icon, and filter with "remote". It won't show you if it is in a container, but you will know if it's fallen behind the couch.
