Hi, before this i just want to say this is a really cool map and i had fun beating it. There may be a problem with the keys though, because while trying to continue my main game -- i wasnt able to unlock locked doors, primarily the one on chapter 2 act two (i think?)
Ill try uninstalling the map to see if that fixes it, because i also noticed the keys are in your inventory -- and that may be the cause. will edit if that's successful

Just making this to inform.
