I had the exact same issue. Try removing the Civ7_CenterCapitalMod. I removed that one (and Treasure Lens which I don't spot in your mod list) and now it works fine for me. With that mods active all of my mods would also all be disabled when loading a save. See this
reddit post for more details.
Mods that don't affect save game, like UI mods, won't appear in the list on the right of your screenshot. Because they are not essential for loading that save. And adding such a UI mod to an existing save is possible. It should be available when load that save, unless the first mod changes something similar and they conflict.
I am 100% sure the Bugfix mod (on left it appears enabled) is NOT active on my current game, because I can tell from in-game. (e.g. it fixes civilian movement w/ Evanglism card, but I see no change so I conclude that mod is not on. I can double check log files etc if further proof needed)
Neither mod changes UI. You're saying I SHOULD be able to load the second mod, but it's not doing it.. I am OK if it doesn't appear on right hand side, I just want it to load at the same time with the other mod.
(P.S. I'll be grateful if anyone can help fix this because my last game I had to drop because of a game breaking bug in Exploration age. (which is why I need this other mod). I am not talking about some little annoying bug - talking about culture skyrocketing to 1,000 a turn in one turn that breaks the game... don't want same thing to happen to this game too.. link to details available if interested)
To summarize, here's the issue I'm trying to solve:
1. Started a game with AI mod, shows and loads fine, no issues
2. Also want to
combine/add the Bug fix mod (super simple mod) to ongoing game. (in other words have two mods on at same time) Installed but won't load when I load a saved game. Only the AI mod will load. (see screenshots above) I can verify in-game that the Bug fix mod is not loaded.
(if I start a NEW game it does list both mods so it works, but that is not my issue of focus. I want to enable to mod on an EXISTING game)
3. Someone suggested changing <AffectsSavedGames>1</AffectsSavedGames> from 0 to 1 in the modinfo files for both mods, which I did. Made no difference. (also set both to 0, no difference)
4. What to try next?
If what I'm trying to do is not possible then that's OK, I’ll just give up. Just want to know what's possible - heard conflicting sound bites
