Same thing happened to me. I kinda stopped dating anyone in the game because of that. I got like 1000 love points for this girl, didn't date for 1 day, then BAM, 20 stars to fix relationship. No thank you!
I liked how they increased the level cap, but it seems useless for motivating me playing apart from a single energy point per level up considering the highest level clothing is level 18. We need more high level clothes, for men that is.
