Correction: This bug exists when only this mod is activated, not just alongside other mods. Devil and angel rooms exist and may be entered any of the usual ways, but they do not have actual graphics for their doors, meaning that they are easy to miss. I would tend to assume that this is not working as intended, but the other parts of the mod- the characters especially- make me loathe to disable it. Is this some issue I can fix on my side? If not, I hope it can be patched soon. Everything else has been fantastic so far.
