Lost EVERYTHING!

My wife and I were playing on a world she was hosing on here PC version. I exited the game normally and hers went into timeout when we paused to make dinner. When I logged back in, I had lost EVERYTHING!

My  character was like new (no XP, no items, no inventory), but spawned near her location (no where I logged out. 

This is a CATASTROPHIC DATA LOSS bug! I know of no way to restore what was lost as her game never crashed or exited. There is no save/restore point to work from. 

Please advise.
