This mod is for vanilla FO3/FNV only, it does not and will never attempt to fix TTW issues.
This new version will require a new game. If you don't start a new game and have issues I can't help you!
I'm not much on making big sexy mod description pages, so I'll just say 99.5% of the credit goes to Yukichigai and his upstream sources (for YUP) as well as BenWah, Quazzy, and hairylegs222 and their upstream sources (uUFO3P.) Additional credit goes to AWZ, DekoMan91, sesom, tunaisafish, & Urbex and of course the TTW Team. Without all those people this mod wouldn't exist.
This mod is an all in one bugfix pack built specifically for TTW. Nothing else is required.
This needs to be as close to the top of your load order as possible. Right under TTW.esm would be best.
Note for everyone who doesn't read the description:
This does not fix TTW bugs, it fixes Vanilla Fallout 3 and Vanilla Fallout New Vegas and their DLCs bugs, you still need the TTW Hotfixes located on the bottom of the TTW Alpha Download page. --Risewild
