So yesterday I decided to give it a try and walk in ME2. (I can complain about walking itself for days, but this is not about it). When I was doing so i suddenly jumped into the air and got stuck. I laughed a lot, made savegame and reloaded, but was still in the air.
So I reloaded a level from the start, and walked again, after some time in a different location it all happened again.
Is this bug actually "works as designed" so that we will not use this idiotic walking?
