Basically just a hotfix to 1.7, fixing a pretty bad error that could prevent Russia from annexing Ukraine.
Also adds Zachadia, I believe, as that wasn't in the last version.
Installation: Open your Victoria 2 game files (if you bought the game on Steam, right click on it in your library, click on properties, then on 'browse local files'), open the NLR zip file, copy the Napoleon's Legacy Remake folder and Napoleon's Legacy Remake .mod file to the /mod folder in your game files.
