Currently memory pools are the most problematic and biggest cause of issues, as far as I am aware only vehicle pools are currently the least functional. Ped (npc) pools should be working fine, but this need be tested by playing with a trainer, menyoo in particular will show the issue of multiple story npcs spawning. In layman's terms, vehicle related mods and features are broken and cause crashes.
