All crit chance gone due bugg

Hi.

I was playing in the game, and suddenly I did no more damage. When I checked, almost all my crit chance was gone, as well as part of my crit damage. Other nodes in the skill tree don't seem to be working anymore (things like reduced skill time).
This bug totally bricked my build, so I can no longer play. I already tried to respec the entire tree and tried as well to take off all equipment without any success.

My dps went from 1mil to about 30k

Any idees
