I personally haven't played the mistlands part of it yet.
I am starting a new streaming playthrough from the start in a few minutes on my discord group to try out everything again on a new seed ( seed name " sherican " in case anyone wants to try it)

but so far i really haven't had any issues with the new update except for occasional game pausing when its not saving. i do still have my original character from before mistlands update and have transferred her over to a new seed. but its not the same experience if you do it right from the very beginning with a fresh start.

but so far I'm liking the new update, minus any bugs ill eventually come across.
