While attempting the mission Chilled to the Bone, I entered an already-established party. It turned out the person had entered an elevator, causing a glitch. After 20 or 30 seconds, the elevator went down without me, and my game froze. I am now unable to log on to Spiral Knights through Steam without freezing and needing to close the game, which is why I am submitting my report here. Support, help, or advice?
Reinstalled, works fine now.
