So far, I’ve encountered two.
The first is that we are supposed to be able to chat to each other in the dropship while the mission loads. I can say one thing; and then it’s done. Can’t type anymore. The chat panel doesn’t open.
The second is still encountering Diamantine drops that are stuck in the terrain. Last one was in the big train station that was being used as a hideout (sadly didn’t get a screenshot at the time). It was inside one of the dark, collapsed stairwells in the corner.
