Get Over Here has a bug that's been fixed now, but in the public version I think it will only work in the hallway when you first load in.
Have not heard about Waterballoon Fight not working yet, sure you doing it right?
I was doing them right. I just had to reopen the game and I got the “Waterballoon Fight” achievement! But for some reason, I still can’t get the “Get Over Here!” achievement.
Edit: I got the achievement but I noticed when the cat ears are equipped, some of the characters have a random hole in their tail. It’s hard to see in the photo but if you look close enough there’s a gap. Not sure if this is a known but or not. Also one of the girls I saw with glasses had her glasses moving a bit weirdly.
Edit 2 (I’m sorry for talking so much-): Is there a possibility we could get an achievement for catching every single girl? That would be lovely.
