In two different mods the outside world does not let me stand, I fall through the mod to water first and then if I don't TCL, I think I'd fall out into the black part of the mod. Both have water as a base and I think that is why i hit that first. I am thinking it may be from having my LOD's from other Mods like frostcraig loaded. Now I am not complaining about that Mod or any other as i find the folks who build these do an amazing job and keep a game alive for more time than anyone ever thought possible. Thank you folks, all of you. Back to the problem: The other thing it might be is I turned off the border so i could go outside of Oblivion borders for some mods. Example Kumiko Manor. The two very large Mods I am having problems with are THE LOST PROVINCE OF ZEDAR, this being the most current one and the other is The Lands of Solstheim-Vvardenfell-Mournhold . But in Nascosto Isles 3, I am not having this problem and this is pretty big. I have 4GB RAM, I am on Vista Ulimate, and have a Gforce card with 512 on it. I think (I am at work and don't have my specs) it is a 7800. ANy help would be appricated and I will update this if I find a fix. Thanks

Well I fixed it. Turns out it wasn't anything I thought of. I had forgotten I turned off Atmospheric_Weather_System SI-14601. In the Oblivion Mod Manager it is at the top as AWS-Core.esm. I turned it back on and right through the ground I went. Turn it off and I am on solid ground. Hope this helps anyone else
