I already finished everything already, home harem with all 5 girls, all collared. The only girls i haven't done is Harmony and Emma. and i guess i messed up. Because her heart is stuck at 96 (there's no way to increase it even using cheat)
oooh!!! In that case it's a bug. I didn't notice before but I have seen this one in one of my playthroughs with Sam as well. It can also happen with Bree. I recommend you tell Andrealphus so it gets patched up. I thought they delt with it but I guess not. It's been around since 3 or 4 updates ago.
Ah i see, thanks for your comment. Because i thought i was doing it wrong, it's fortunate i have another save that all home harem girls have 97+ hearts so i can do the full harem ending.
