Hello,
this DLC crashes my game always to desktop when I come in the near of any Clay Deposits.

The Unofficial Hearthfire Patch-25127-1-0-3 doesn't fix it.

Is this an unknown problem, that only I have, or is there a fix for it?

All my other mods are not the problem, because when all mods are deactivated the problem in hearthfire is still there.
