I'll see your Error 90000 and raise you the evolved form of it: client crashing.
I posted about this before (
link), but basically I tried progressing and doing stuff, non-instanced stuff, while still under the effect of Error 90000. Well, it seems to have pissed the lobby or data center or whatever right off, and since logging off and trying to log back in yesterday afternoon, my game crashes like clockwork when I try and enter the lobby/character selection screen.
And worse, I know this is related to character corruption as well. How? Well, for one, I tried a full reinstall and that did nothing. But most damning is that when the NA/EU servers were down, I actually *did* manage to get to the lobby. Was even able to test and make a new character on a JP server for an hour late last night during the emergency maintenance. But once that ended and NA/EU servers became available again? Yep, you guessed it: crash and burn.
I'm seriously scared that this won't be resolved in time for early access, let alone ever, since I've yet to see anyone have a similar evolution of the Error 900000 issue that I am now having. I had a friend who E9'd, and I asked her to basically try and do what I did and see if it caused their game to ***** up like mine did. It didn't.
