The issue i having is Real Side Memory Navigation fills too fast at the beginning and it turns into untracked memory, sometime it stops filling and stays at 3 gb and no longer rise.
But it didn’t work, i tried to edit real side, but it fails to load and only way to fix it is to restart roblox studio to fix.
I’m tried to solve that issue but it seems to be impossible to know if scripts or map size affect Server’s PlaceMemory. 
Trying to solve that issue consumed my time, 2 weeks after map expansion + npc’s pathfinding upgrade [removing waypoints when npc reached the final path] and the issues wasn’t fixed and it kept crashing if i try to test / play with friends.
