I have seen that as well -- which is why I think it -is- loading and active.
when I get a chance, I'm going to create a "slightly modified" version that gives a visual clue that it is loaded. I'm thinking about merging with the mod that removes the 2k logo from the top of the screen, as that would never be in any conflict and will be an easy clue for me if it didn't load on a save.
Or one other thing that
@notque (or roman holiday) could do is just put a version # on the top row like Roman Holiday has on his Civ 6 AI mod -- then it is easy to know that it was loaded!
