6. I got what you mean. It only happens for dialogues without any follow up. I think it was like that since the beginning.
9.Yes, Ena's animation doesn't appear second time until you reopen the game. Will fix that one. As for Mei and Masuo could be because you made wrong choice in her quest.
10.This is one of the annoying one if you don't do layer management well. Doesn't happen for millennia but that one day.
Custom NPC code doesn't work for the version I've given you guys but this is possible with custom npcs.
