Does this mod conflict with UL? I just started TOTF and I can't find the ruined Ehothorn Estate to save my soul. I've read the guide and it says that the marker is intentionally "off". I've searched and searched and even turned off the trees to find the place and no go. I'm now thinking that another mod I'm running (I really don't have that many) must be interfering... possibly UL, which I have the complete set.

Yes, there's a conflict with Cheydinhal Falls, and there's a patch for it to clear everything up.

There's a compatibility patch http://www.tesnexus.com/downloads/file.php?id=13834 for Tears of the Fiend and Cheydinhal Falls. Not sure if that applies to you or not.

Thanks. I didn't see any patches on the Nexus. I'll look again.

EDIT - Thanks for the link, sommner42. I really appreciate it.
