I'm about 2 months into an IronMan game of XCOM on PC, and I hit what appears to be a game-breaking bug. I entered an Alien Abduction mission, and I don't have sight from any of my squad members. I can't actually see their models, but I can see the UI indicating where they are. I can't tell them to move anywhere, though I can put them on Overwatch (which doesn't help).
In short, I'm stuck.
I do have the option of aborting the mission from the ESC menu, but I'm not sure what Bad Things that will entail on IronMan.
Is there a way to fix this situation? Alternatively, if I abort, will I be able to get back in without penalty?
