About 8 months ago, the dev (Jackson) posted this file on his discord server. It's currently the latest version available, though it's still WIP, so it may feel incomplete.

Here's the download link: https://mega.nz/file/zdJGWJgC#YiaFHmofs74FwXGpwmK3Zj_1y7m3azMAYC0cZrvCPFw

Do note that it is NOT save game compatible.

The discord invite link on the Steam workshop page no longer works and for some reason the dev disabled all invites. Nobody except him can generate a new invite link. However, he is still working on the mod. He's mostly offline, but every couple months or so he posts some pictures of his progress. The latest update was less than 2 months ago, when he posted a new screenshot of Norwegian grenadiers, and said he's currently trying to figure out how to fix a strange bug that makes troops appear naked when it's raining.
