I'm also having a bit of difficulty with both cover and concealment in CM:Norm. I was used to CMBO, CMBB, CMAK and Farmville. As an expert in Farmville, I found that a surplus of livestock might help. I was spoiled for years with heavy forest, light forest, etc and dropping down to eye level and I could see the depressions in the ground. Its a bit more difficult for me now with CM:Norm but am hoping to adapt.
