Guild bank items missing as of today

It seems to be hitting a lot of folks now. Please add your issue to this thread:

Guild bank missing items - what happened?

I opened one of my guild banks and found that a good two-thirds of the items on each tab are now gone. The icons aren’t glitching; the slots are literally empty. I am the only one with access to any of these guild banks, and everything was fine five hours ago when I last deposited items. Is anyone else having this issue? Please tell me this can be fixed.
