Yea I figured out manually placing the esps from the zips, seems bad packing from their part. SMIM gives me some missing textures (smelter coal pile, some wooden stake formations mainly at watchtowers), which I find strange as it didn't do that with an older version of MO. Author of SMIM has noted that problem on nexus and just says, don't use MO : well, I can live without SMIM, but it was strange to run into that when I know it worked before.
