My bank space was reset sometime between 11:00pm and Midnight 4-6-2014.
After playing on my main for ~ 1.5 hours, I logged into an alt that I had started to level on the starter island (Khenarthi's Roost). That alt had originally been an "unleveled" character that had bypassed Coldharbor. That same alt had oddly lost access to the guild store since going to the starter island. Initially upon accessing the bank with the alt, only 4 blue items remained of the likely 50+ items that had shown as stored in the bank only moments ago on my main. Further the banks size had been reduced from 80 to 60.
When I logged to my other characters (including level 3 alts that had bypassed coldharbor, and my main) the items (or at least most of them) once again showed as being in my bank. Similarly when I logged back onto the alt leveling in Khenarthi's Roost, the initially missing items also showed up in my bank, but the bank size remained reduced.
My bank space was 80, it is now 60. I don't know if I lost any items.
I had been playing continuously for ~ 1-2 hours, only briefly logging between alts to store items.
At around the same time, I noticed I had been sent a second/duplicate round of bonus items (pets and treasure maps) via e-mail from customer appreciation.
