Unable to move, jump, or look around.

[Quantum]

As the title states, I ran across a bug that prevented me from moving, jumping, and looking around.  I was in the Pot Dog Shelter dungeon and everything was fine up until I got to the boss.  Right after I attacked the boss I suddenly wasn't able to move, jump, or use my mouse to look in different directions.  But I was still able to attack and use the Q, E, and SS skills.  Also there weren't any debuffs on me at the time.  Luckily I was able to defeat the boss in this state somehow (even after getting hit by a few bombs and stunned a couple of times), but after defeating the boss I was still unable to move/etc.  I had to windstride to get out of the dungeon and everything seemed to work fine afterwards.  Also I was playing as a Blade Dancer.

Same problem here, encountered when trying to fight Yutan - mouse stopped respoding and only keyboard controls were useable. I died and the mouse returned only around a minute after the resurrection. I was playing assassin.
