Okay, so based off your list of mods you just listed, you are
NOT using NatDiv and NewFlora and for that matter not even ForestOutpostNatDiv like you said up above. So I will go ahead and remove those as well I suppose. I want my thatch to work as you described above - so I will match what you do.
ROFL, I was like you before, especially when I first joined here; I played with hundreds of mods installed! Haha

Now I am down to 17-52 at most now. My current map I am trying to set up like yours is the RKEC+CC combo and I have 52 installed and if I remove those 3 above then it will be 49.
Isn't that SeasonFX mod killing your system? I would think so, no?
You do have some mods I haven't seen before or heard of. Care to tell me about them and share any of them?

The mods I
bolded above sound
very interesting.
I have a terraform tool included with CCTerrainTools but CC itself only has the ground flatteners so if I include the CC Terrain Tools with CC then I get the Terraform tool but then I have duplicates of both ground flatteners. So I am hoping your copy of Terraform is just the Terraform part itself without the ground flatteners. What is CloseToTheEdge?! That peaks my curiosity!
At the very least I hope you are willing to share
the ones I bolded.
Thanks Brad
