I have been reading a couple issues about a conflict arrising in these three mods resulting in NPC's and vendors/merchants staying in doors. I have just run into this issue as well with a Step: extended install. I was curious if anyone else has had any issues running these three mods? Going through them with TES5Edit, I am no expert, it looks like Wet and Cold is asking vampires to go indoors in the rain, while Run for your lives is indicating the same to NPC's. Anyway, I don't really know enough about scripting/modding to go into TES5Edit with any confidence to point out errors. I am thinking about just going with a Core install for now, but figured I would bring the topic up. It looks like Isoku, the author of Wet and Cold has told a poster on the nexus he would look into it, and Arthmoor, the author of Run for Your lives is also aware of the issue. Edit: Resetting the mod through MCM and waiting 24 hours seems to have helped some of the merchants come back out.
