Running into this bug on the Android platform, version 4.0.3.
Playing on a Transformer Prime tablet.
On the Beraza Bandit Pits quest during the underground battle; Shigaz will suddenly stop moving after performing the Shadowstep.
He will usually take damage and die after this, but if I keep healing him and finish the battle alone, he simply disappears.
The game is unplayable beyond this point as my character is trapped, and the story cannot continue.
This quest is part of the main storyline, and cannot be skipped, as suggested by Apportable.
Reproducing the error is simple, it occurs every single time this battle is played.
Kind of a major bug...
