I am making a mod with a new worldspace and as the title says the game and the geck are crashing when tI put too many NPCs( around 50 ) in a single cell

Any help will be appreciated

Have you tried cutting down on the number of NPC's in your worldspace? I know there is a given number that is to much but, have yet to exceed it myself.

I would love to know what the limit is.

50 is not that much if it is an interior cell. In exterior there are other parameters to take in account, so the number is often less. Try to always stay under 35 in each cell, interior or exterior.

But even with 30 don't expect to give them individual complex AI. With more than 6 or 8 NPC at the same time you have to stick with very basic AI package or they'll just ignore it.
