Hi guys.
I'm also having this problem. It seems to be a certain type of road block which is creating it. As some road blocks spawn with the correct units. I'm currently trying turning off the ambient vehicles option to see if it has any effect. It seems to me that all the instances where vanilla units were spawning they had a vehicle nearby ( of course it could just be a coincidence ). I have tried it with both car aggressors and CUP Takistan militia.
I also noticed the random camps option is being rather zealous about placing large camps which are integrated into other large objects. In a 24 hour period this has led to a water tower on the edge of a very steep hill and lighthouse in Takistan. Is there any way to control the composition that alive will use with a certain map or fraction? (without scripting since I am a dummy)
