There's a spot in the Farmlkands that on 3.1 would trigger a "nighttime fun with moohmins" but in 3.4 that doesn't trigger, and instead causes the game to glitch up (possibly because the writing being slightly off), What happens is the player location disappears and you can't really do anything Fixable if you have a fast travel spot available, as it transports you to new land and things continue. More "annoying bug" than anything, but the player loses out on finding out just how intelligent moohmins are and the prices of their silence that you were in a spot you shouldn't technically be!
