Noticed 2 bugs while playing this game:
1, During the first 2 affection levels (before she undresses to her underwear), when you get kicked out of her room after watching TV, the player model goes invisible, and it doesn't return until you interact with one of the women or with the nighttime shop NPC (interacting with the MC's bed doesn't restore the character model)
2, If you have ordered Jay to "Follow Me" and she's still following you when the next "relationship level up" screen activates, the "Follow Me" feature becomes permanently broken, with Jay asking "where are we going?" but no longer moving from her 3 normal locations washing dishes, watching TV, and sleeping (as shown in the cutscene by 2 Jay models overlapping on the bed, with the bugged instance lying directly in the center while the intended instance moves around throughout the scene)
