The mod in question: http://www.nexusmods.com/skyrim/mods/60028/?

I was told that adding new spawn points and/or duplicating it may cause issues when used in conjunction with additional enemy encounter mods. The classic example is SkyTEST + Immersive Creatures. SkyTEST adds new spawn points while Immersive Creatures adds new encounters, thus opens up the possibility of causing issues (like CTDs).

Is there any truth to the claim?
