so I'm at the milking place on the mountain, and right after i beat the boss and the bridge is built it doesn't let me cross, and if i go to leave the room it starts the whole encounter over, the demon is still with giant boobs in the water but the speech bubble still shows up where nothing is, then the battle happens again, she gets beat, bridge is still broken, and so on and so forth. Tried loading past save and issue is still there, am I missing something?

I manually moved the MC via save file editing and the sequence can indeed be completed, but doesnt really lead to anything

i have loading error "failed to load: img/characters/$cowgirlyellow Bust3.png"
