i think with Marty fiddling code for some gallery implemented into the game, things for the mod might get messier for the next updates.. might still be a good idea to show him your mod? probly could speed up things, since yours is in working condition and only has to follow content updates, more or less.
-oh and.. if you're really.. beware of Romans. aaand crosses and all that.
assume what happened here is, that he simply kept throwing new content files into the same old (maybe his first) folder. for my taste, that path is way too long, too.
i might be wrong though.. the Ren'Py version shown in the reports is quite old. it should be a 7.4.6 for the actual build.
