A few bugs. So after importing as I wanted to keep items and guild stuff even if losing all characters, it saves, but on the main screen still shows the waring of this is a older save when booting again, so its not updating that it is now a 2.4.1 save, everything saves and loads fine, just that that warning is left.
Now one thing that isnt saved is the other bug, if you locked adventures in as maids or tavern it does not keep them locked upon loading so you have to relock them. I am assuming this isn't tied to updating a save, but it could be. Also could we have the lock option in the training grounds, when I am leveling stats I often do it back to back with waiting, so locking them in the job slots even if I have to reselect which stat would be nice. Hell there is objectives that ask for working at training or patients that it would be nice to keep them there. Ideally you could lock them in with currently selected stat to be trained as well as just in general locked in.
The last bug is which the levelup commanded, I tried to level up a prisoner, but nothing happened, I used the command in 2.3 after you mentioned it and it worked then, so looks to me like it has trouble raising the level with the new way they are saved.
also this was a oddity, on a prisoner they were able to use orgasm with belt of denial equipped, later put it on a cleric and it blocked them from orgasming as intended. If I replicate it again will update further.
My party order has been just randomly changing constantly, Its really odd, changing the order out of combat only changes it for a fight and it just reverts after that, moving them in the fights also isn't saved, perhaps a move or somthing changes the positions in a way that is persistent.
Estrus is missing from the tool tips
Had a prisoner with the goal start 20 turns blinded, they were blindfolded but it didnt go up at all, dungeon was high enough level and another goal was completed in that run so was just that goal.
