Okay … either I did something really wrong (quite likely I know) or your missing the mod on the latest download.
Backed up characters first. Downloaded and installed both Grimarillion and ungrim. Didn’t see a message saying replace files when installing. Checked ungrim and still v60b. Decided to delete both folders from GOG Galaxy/Games/Grim Dawn/mods and reinstall. Checked again - only base game/AoM masteries to choose from. Thought oops, better install some back versions as something must be missing. So reinstalled V59, v59a, v59b, v60, v60a, v60b and v61 and did see the replace files message all the way through. Back into the game - still the same, only base game masteries to choose from. There is no mod. And yes, I’ve chosen the mod ingame under Custom Maps. My L35 Guardian of the Elements has no skills, although the quests are correct. Also no version number anywhere that I can see.
Deleting folders and reinstalling ungrim from v59 to v60b does not solve the problem. Still no mod. What the hell have I done?
