Well, for anyone still waiting for news on this. Keep waiting.
My bugged char was only level 6, so took a chance and logged her on in.
She was empty EXCEPT for:
A Totemic Staff of Splinterskull (in backpack, and had been locked)
A Rod of Moderate healing (in backpack, had been locked)
The ExPac pre-purchase goodies.
Her mail was still in mailbox (Lottery wins)
She was unable to open her bank, so not sure if there was any effect on her stored stuff.
Also of note to devs: Even tho her equipped gear was gone, the armor kit I'd bought for her was still showing both on her in game, and on character select screen after I logged her out.
