This time is noticed that you can’t attach any sloped inverted walls on the curved ceiling pieces. They just won’t snap on.
So as far as i know the remaining issues with the Aesir build set are the one mentioned above, the sloped roof corner not aligning properly if you try to replace another one with it and the fact that if you replace/upgrade other ceiling pieces with the Aesir ones everything that’s placed on top of them will be returned to inventory. Every single work station, decorative item, everything.
There might be other issues as well but haven’t come across them yet.
