I don’t get what you’re talking about regarding the “Online” map. What mods load the Online map? Single Player Garage and Home Invasion? I’m not using Open All Interiors. And what is the Online map anyway? Why would they load the map from GTA Online?
From my understanding, the reason why mods like Single Player Garage, Home Invasion, and Open All Interiors remove other blips from the map is simply that they add so many blips to the map, and the game has a hard-coded blip limit, so if that limit could be heightened, my problem would go away, unless I’m mistaken.
