I'm working my way through the quest called "The Hole". My current task in this quest is to recover a book stolen by bandits. They are in an underwater cave near Lord Rugdumph's estate. The Underwater Cave does show up on my map, however, I can not find it at all. I swam all over the lake looking for the entrance and it just isn't there. I'm thinking there is a conflict with one of the UL mods I have installed.

Has anyone had a similar issue?

I will probably have to abandon the mod and move on to another.
