I am unable to use the digivice for some reason now, as every time I try I'm unable to do anything once inside the digivice. I first encountered this when trying to fight the midboss in the fleshy area.
One more thing, I think I've beat the game now (or whats out so far) and I cant view the momma rena scene after giving her the gift. The photo doesnt show up when giving her the gift and when I try to view it in the gallery it still tells me to explore and find the gift.
Tried to load a new save file and use the skip crystal to get back to the kuro area and had the same issue.
