paralyzed while not paralyzed?

[Godofgods]

Could it be you accidently moved without noticing like bumping your controller or something and so casting was interrupted? Maybe that's a dumb assumption but it's the only thing I could think of.

I play with keyboard.
Its not a bad assumption, iv always had concerns with interruption while moving. Example: If i need a spell to go off but accidentally take one step, its always interrupted. But if i run around in large circles a couple of times the spell will always go off. 0.o lol

But it happened several times while i was their. More then i would attribute to accidentally moving.
