In this case, it was in fact an oversight for solo characters. Other dialogue issue may be dependent on specific characters, tags and quest states, though, so it is better to add more information than needed than not have enough to reproduce the problem.

There is a known issue where buffs and some polymorph skills can stop working (a save/load should help), which should hopefully be fixed in the next update (no ETA). One issue was found which could cause that, anyway, and if there are any other triggers, QA should catch it while continuing to test the game.
