Since the guild hall update, myself and a few other players have been experiencing both or the latter:
- Spiral Knights terminating itself instantly
I personally noticed this happening occasionally in months prior to the update, but it is particularly frequent now. It commonly occurs when alt-tabbing, particularly during loading periods, and may sometimes happen without any suggestive triggers.
- The game, particularly after a crash of the above, will cease to load properly upon logging in, never reaching the character select or loading the level
