Yep. Had to figure that out the hard way. I noticed that the 1.5.x version didn't have that AE ad on Main Menu and I saw the option to turn it off in BethINI so I turned it off to emulate how 1.5.x look on 1.6.x. I haven't tested thoroughly if just turning off Modding Platform precached all the grass correctly. I only tcl'ed around whiterun area with dyndolod grass ON. So far, every area expected to have grass has grass or grass LOD (compared to having Modding Platform turned ON which have huge patches without grass).
