Did you guys make reports through the support center prior to now? I recommend that everyone needing to reset their 1.0 import make a report, that way SE's aware it's an issue people are stressing about. Be clear that you need a reset of your character to fix the problem, or mention specifically what it is you need to change that a name/appearance change alone won't fix.

There might not be an official response or solution for a while, though. In the meantime, make fresh characters to pass the time and don't touch your 1.0 characters.
