Hi there,
When you try to put a Lore item in the guildbank it gives an error about not being allowed to, but the item disappears off the cursor rather than allowing you to pop it back in your bag.
You can log out and back in for it to reappear.
There also seems to be a buffer limit on the number of items that disappear. I was dumping loads of stuff into the bank and stupidly kept going thinking i would deposit all the ones i could, and then get all the ones i couldnt back when i relogged.. but i definitely didnt get them all back.
Not asking for reimbursement on these though, i couldnt guess what i lost.
Thanks.
