New mod list causes crashes

If you are asking for a link for the Options File Editor then I can only guess that you never changed it from false to true in the first place as it would just be a reversed procedure.
I totally agree with Sailor Steve. It's a pain but sometimes it is the only way. I started with 74 mods and although everything started ok I started to get ctd's to a point where even the saved game would not load. I decided there and then that I had had enough, so I decided I would only enable the mods I really could not do without and still ended up with over 50 mods and no ctd's to date. I took the trouble to look at mod lists from 6 other subbers rather than just the one to make sure I was on the right track.
As I said before I think you could lose a few environmental mods and not notice the difference. If you look at the readme for the Dynamic Environment v2.9 this is a really good mod with a lot of content. I just wonder how many mods you have that are over writing other mods!
