I only encountered what seemed like bugs twice.
First was in the tutorial mission with Harec. At the point where you're directed to use his teleportation move, I did as instructed and seemed to end up outside the map. All I could see was what seemed to be the outline of structures in orange. I mashed the buttons and eventually returned to the map. I was going to try to recreate it this afternoon, and record it, but I didn't have the time to get on.
Second, I was playing solo on the map where you have to overload the three reactors. I was able to activate the first one, but wasn't able to activate the other two. The button prompt didn't show up, and nothing happened when I pushed the interact key in front of them. I died a few times and respawned, and still wasn't able to activate them.
