Trails Of Cyrodiil Complete - Ancient Redwoods, Brena River Ravine, Cloudtop Mountains, Colovian Highlands, Eastern Peaks, River Ethe: Created by mhahn123. 
Verwen Brewery Replacer ESP created by mhahn123, to be used only if also using FB Dark Crusader, Ancient Yews, Arrius Creek and the Ancient Yews/Arrius Creek linking patch. If you use all of these mods then replace the Verwen Brewery ESP with mhahn123's version from here. You won't need the UL compatibility patch for FB Dark Crusader
Waalx Animals & Creatures - The Lost Coast: Created by Derridar, available here. Do not use the other patch provided for Let the People Drink and Imperial Isle, there is no conflict between these two, no patch is needed
Windmills Project Ambience - Unique Landscapes: Created by Xamie, available here.

Brewhouses of Cyrodiil - Snowdale... The conflict is so minor it isn't worth patching. One large rock within each of the two building meshes slightly sticks out through the buildings. Use the console to disable them.
Castle Arpenia - The Lost Coast... The conflict is so minor it isn't worth patching. There are a few trees which grow through the approach to the bridge crossing to the Castle. Disable them with the in-game console to resolve.
Dragonfire Trade and Transport - Snowdale... The conflict is so minor it isn't worth patching. Just a few pathgrid nodes pass under the building.
Hashshashin Armor - Cheydinhal Falls... The conflict is so minor it isn't worth patching. There is a single tree slightly overlapping with a single burnt tree from the armour mod. Disable one of them with the in-game console to resolve.
Hillsborough Estate (by Nachor and others) - The Lost Coast, The Heath, River Ethe, Ancient Redwoods, Chorrol Hinterland, probably others... Have you SEEN this mod in-game?! It's MASSIVE! I'm not even going to try to patch this, my sanity would crack. I see this mod as a complete overhaul of the west half of Cyrodiil; it redesigns Anvil, rebuilds Kvatch, adds a new city, adds some large walled-in areas, new villages, new forts, new houses in the wilderness... It actually appears to have UL River Ethe and possibly part of Chorrol Hinterland merged in. If you want to use Hillsborough Estate, you can't use any UL it overlaps with.
The Mysteries of the Dulan Cult - Cliffs of Anvil... The Dulan Cult mod is a little messy and includes some broken scripts, making it slightly risky to use in-game, thus I will not create a patch for it. However, Better Cities includes an altered copy of the Dulan Cult ESP to make it compatible with Better Cities. The BC replacer ESP for Dulan Cult is cleaned and should have all scripts fixed. Dialogue has also been spell-checked, and edits have been made to make it fully compatible with Cliffs of Anvil. So users of Better Cities can use Mysteries of the Dulan Cult with Cliffs of Anvil without suffering any conflicts.
Order of Nibenay - Snowdale... The conflict is so minor it isn't worth patching. Just a few pathgrid nodes pass under the building.
Order of the Dragon - Panther River... The conflict is so minor it isn't worth patching. One rock and one tree from Panther River overlap with a rowboat and the side of a ruined tower. Use the console to disable them.
RealSwords Breton - Skingrad Outskirts... The conflict is so minor it isn't worth patching. Two horses don't stay within the small fenced area as the pathgrids are overwritten.
Sage's Skyrim Armory - Snowdale... The conflict is so minor it isn't worth patching. One large rock within the building mesh slightly sticks out through the building. Use the console to disable it.
Trails of Cyrodiil - various... mhahn created around 30 compatibility patches for Trails of Cyrodiil and Unique Landscapes, which are still available for pre-v2 ULs however mhahn advised me not to update his patches for v2+ of Unique Landscapes as he is working on a revamp of Trails of Cyrodiil. Patching will wait until the revamp has been released.
TWMP Skyrim Improved - Snowdale... The conflict is so minor it isn't worth patching. Some steps are slightly covered by snowy ground.
Wicker Man - The Lost Coast... The conflict is so minor it isn't worth patching. There are two trees which grow close to the wicker man. Disable them with the in-game console to resolve.
Wonderful Lake - Aspen Wood... The two mods are almost the same size, and both are landscape overhaul mods. It would be pointless to try to combine the two as each is entirely different in aim. Pick one or the other.
