Some mods don't have Art, and only have Text descriptions (much like some of the Enemies were in the vanilla game in the past prior to Art being made for them).
I'm more curious about how you got Mods to work on the Android version. Did you simply make the Mod folder in the folder of the game on Android and put the Mods there? (since I didn't see any Mod folder by default on Android in the specific folder)
Yeah, pretty much I just did that and then updated my save just to be sure. I remember there being a guide on the modding page on how to put mods in the game.
It worked on other versions of the game before, however I think it is really not working with this current game version.
Still, I can use the mods, items, and also get to the story quests. It is just the photos that are not showing at all.
