There is a few situations, when destroying the object doesn't remove solid texture of it (im not talking about walls or the like, which are sometimes bugged).
After destroying Vox caster, Stationary turret and napalm thingy, even though they are destroyed, you can't move through the place where thay were located. Im not sure about healing tower, probably the same.
Also, on the City of Suffering map, you can't move through places where Pain Catalyst spawns.

Another issue regarding campaign. Klosterheim investigation, clues 0\6 (when you arrive on the Martyr for the second time and first mission is defence mission). After you proceed with the tasks, character experience so-called flashback, seeing Klosterheim showing admiration to the player. I tried skipping this, actually skipped the cutscene, but COULDN'T move afterwards. I mean, game just dont realise any inputs, character doesn't rotate, doesn't use skills and the like. So i just had to retry the mission.
EDIT: bug was encountered while playing as an assassin. Tried to trigger the bug again - it triggered when I performed dodge. My speculation is that it (bug) can be triggered while doing some movement technic (could be movement skill of weapon etc) AND entering the cutscene at the same time.
