It seems that every time having completed a mission the game will crash if, I have some sort of active shield. For example when a temporal shield is active, or when a personal void shield is active.
I always use personal void shield (like 5 stacks) and I have't experienced this kind of crash .
So, it's interesting. Are you sure that the shields causing the crash?
I do believe so, as I have only had 3 game crashes as of this time. The first was whilst playing an assassin who had the temporal field running when I accepted the mission, that was a few days ago. The other 2 crashes were today, again when I accepted the end of the mission and, both occasions I had the personal void shield up on a crusader.
For what it is worth and, further to my previous post. :)
I just completed another mission with an assassin and made a point of accepting the mission as complete whilst her temporal shield was activate; the game crashed as before. It would seem to be a combination of an active shield when clicking on that accept button.
