mods that overwrite the api's enumerators (i believe gemstones is one of those mods) have the potential to break revelations and many other mods.

mods that do stuff if the current stage is catacombs will also do those things in glacier and tomb if they arent specially coded to handle it, this can cause some weirdness with mods like quarry.

you may also not have a complete installation, the way the game pulls the mods from steam workshop is absolute garbage and will break often. try a reinstall if doing anything else fails.


i suggest you disable all your mods except revelations and its required mods and see if it's still broken. also posting what mods you use here would be helpful if it turns out to be an incompatibility.
