Hello, I tried looking around for this but it seems my case is... somehow weird? I started using purely cosmetic mods (mostly custom dice) around halfway into my first playthrough, and it seems this was counted as "mods enabled" and disabled achievements. I also installed the "achievements enabler" from nexusmods, but it did not seem to change anything (I think the last achievement I got was for finishing act 1, whereas I already completed the entire game once).
Is there any way to have purely cosmetic mods installed without disabling achievements? I am on GOG, if that makes a difference.
I guess it 's a GOG thing, as I have around 50 mods installed and still got all achievements in Steam. I even finished honour mode wit a party of 8 thanks to the party limit begone mod, and I still earned the Foehammer achievement.
but good to know this is not game-side.
