Skyrim Sewers 4. 12 SSE

by Viltuska

-----------

Version 4. 12 requires Skyrim Special Edition

Updating from the 1. 0, 2. 0 or 3. 0 should not require clean install or a fresh save, but is something I would highly recommend just in case to get updates kick in. To make a clean save, deactivate skyrimsewers.esp/esm, wait 3 days ingame and save, activate the the new esp/esm and play. But as I said, this isn't probably necessary, just a safe caution to make sure everything gets updated. If you are using the BSA and have an older version of Skyrim Sewers installed, you might want to remove these files just to be sure: http://img163.imageshack.us/img163/5250/sewersfiles.jpg

OR download the batch from miscellaneous files.

NOTE: There have been varying reports of instability around Whiterun area while using Skyrim Sewers 3 along with SkyTest (this one more than the others), Grayledge Manor, Build your own home and PL Loot Overhaul. Disabling one of these mods or using Skrim Sewers v. 2 might help you avoid these conflicts. Also make sure that your mods are made for the latest version of Skyrim (atm 1. 8) to avoid conflicts in the NAVmesh department. Also playing on a outdated or pirated version of the game is not recommended with this mod. You might also try the ESM-replacer for Skyrim Sewers, which has helped people with certain memory-related issues. Since I'm no longer able to do maintenance on this mod, anyone is free to make patches and their own versions of the mod (applies to all of my mods).

Description

-----------

The current version of this mod adds an accessible sewer system to the town of Solitude, Whiterun, Windhelm and Markarth (from v. 4. 0 on) and also small sewage tunnels to Fort Sungard and Greenwall. The Solitude system has three exits to the outskirts of the city and several others into dungeons and other buildings. Windhelm has also two main exits and connections to other dungeons. Whiterun has 3 main exits outside the town walls. Markarth Sewers, which is the smallest one has one exit into Left-Hand Mine. This mod also includes 4 custom weapons and some unique books.

Issues/bugs

-----------

- The pit exit to the Pit of Bzarhk does not always work (should work 90% time though). Just ~ + TCL up until you get back to the auto-load door or reload a save above the pit and leap again. Or type in "coc ssewersMRKpit" to the console.

- Sometimes the Skeevers start "jumping around" in narrow walkways. Nothing game breaking, just looks stupid.

Miscellaneous

-------------

I'm trying to apply my modding philosophy on this one as good as I can. That is to create content that fits Skyrim rather than contradicting it. In other words complementary stuff that tries to make t
