To add to this, I have noticed that if I add like three or four MLOs at a time, it doesn’t seem to mess with scenario/gang/animal ped spawns. Once a folder has around 40 MLOs in it, I create another folder and start adding maps to it (I’m not sure if this actually does anything for scenario ped spawning but it does help for organization). I’m running around 120 MLOs right now and haven’t noticed any missing scenario peds because I’ve added MLOs in batches of three and four at a time. A bit tedious, but an interesting way to “trick” the game into letting scenario peds spawn. I can’t guarantee this works for everyone, but it seems to work for me.
