I've been facing this issue for a while and have worked around it by saving and quitting often but I'd really rather get a permanent solution if possible.
The only mods that I use are the two listed above, I've heard of others having my issue, but in those cases if seemed to come from 7th Heaven. I don't use that however. I believe it has something to do with texture memory but I'm not sure how to fix it.
It's likely on Reunion's end but I can't seem to find anywhere that addresses this issue specifically.
