I was doing a beast/shock themed clockworks tunnel level, and managed to get hit by a pair of electrolisk spit blobs. Somehow this managed to lock my knight into the shock spasm animation, and I was unable to shield or move him away from the spit wads, and subsequently he died. (From full health, no less)
I filed an F2 on this.
Ok, this definitely isn't an isolated glitch. It just happened to me again with only a single electrolisk blob. This time I was luckily able to pull my knight out of it and didn't die.
