Spiral Knights has been crashing for over a week now, and not sure what causes this.
A few other players have seem to have the same issue but mine crashes frequently.
Usually it happens while loading to a new zone, a 60% game crash rate. I've tried repairing game files and that's a no go.
This gets annoying when I am in a run, I would sometimes load back dead (won't waste a spark or don't have any), and I would always have to unplug my keyboard before launching the game whenever I want to opt for the gamepad. I notice from the last notes there was "additional login" but I doubt it could be from that since no one hasn't complained about it yet...
Could it possibly be my Java 64bit version?
I have experienced this as well, both with 32 and 64 bit javas.
