So i've been following the guide to the letter, and i'm at the "Unofficial Patch Plus" " Unofficial Patch Plus Author: PushTheWinButton and othersVersion: v1.38Installation: Install both the main file and the optional file. When installing the optional file, select [Merge], not [Replace]. "What is the "Optional" file mentioned? i don't get an option to to [Merge] or [Replace] I noticed the version numbers don't match up. 1.38 is not available on the nexus. Current version is 1.50 with 3 additional compability patches marked 1.46 So should i go ahead with the Unofficial Patch Plus 1.50, and perhaps Unofficial Patch Plus - Project Nevada Patch? Thanks
