2. The corpses of Mairina's brothers. Sometimes both are lying, but sometimes, either both or one of them periodically do not appear in the swamp. What it depends on, I couldn't figure out.
I am not sure if this helps with your concern, but there is a turn of events in which they do not turn up dead. If you just let them go their merry way, you won't find corpses and Auntie will say something about them being at a farm.
It's nice to read that Gale's camera glitches and endgame kiss trigger are worked on, though they are probably not the gravest bugs on the list. I hope that the missing companion reactions to the act 2 visit by Elminster for Origin-Avatar-Gale will also be patched. It is a bit depressing if only best girl Lae'zel (and sometimes Wyll) care about the grave news Elminster delivers.
