I use Mace mod and also get the crash when I am in the mine temple. I found out that the bug is because of the 2nd stair from the temple gate in luculla mine and there is a way to move on without using that stair. The solution is using a teleportation spell( not self-teleportation like ranger or fighter dive) and teleport all the player onto the second floor without touching the stair. I have finished the mine and now move on the next area. Hope that help you guys.
