All Bank Inventory and Purchased Slots Disappeared.

Aargas

I was just in my bank, around 10:40am EDT when I switched characters to add and remove items. Upon logging in to that alt of mine I received a load of ingame mail for pre-purchase, beta and Imperial Edition and my bank was completely empty and reduced back down to 60 spaces from the 90 I had before I think it as 90, I know my next upgrade was just over 11K gold.

I have the same issue here and starting to believe ESO is ripping us off by not repairing a bug that has been an issue for weeks now, People be warned...

I switched characters again and I have some of my stuff now, but still down to only 60 slots and missing what I had over that.

Same me, I got disappear 20 slot in bank at yesterday so I did check it at today and if they did fix it or not but They did not fix it I hope, They will fix it to Inventory in bank.

Same here, I have 90/90 bank slot filled last night and log in this morning to 60/60 filled. I hope they restore both the slots and lost items as some of my legendary/epic crafting items were in the 30 items that disappeared.

They are aware of this issue - its listed on their 'known issues' list.
I thought the pre-order multiple mails was a separate bug, but when I raised a thread here was told it is connected to the bank bug. Do a search - there's lots of us.
They advise not to upgrade your bank but have also said we'll get back what we lost.
