So I found a few more mods that looked promising and I downloaded them, installed through MO, sorted load-order, cleaned some with Tes5Edit and then started the game.
Load up my "explore new mod" save-game, and.....
Get a message: This save relies on content that is no longer available message.
Then when I finally get ingame all "scripts/MCM's/whatever" reloads themself and after some 15 seconds the game starts to kind of flicker (like ultrarapid nights and days, it kind of fade in/fade out). I can do stuff as usuall, it just get's dark ever 2 seconds and then goes back to normal.
Have I reached the limit or is it some kind of mod conflict that causes this? I uninstalled a few mods that does not really add something I want/need and everything is back to normal again. Seem to be the limit. Or?
According to LOOT I have the following:
Active Plugins 254

The two warnings are deletd Nav Meches in Stoop over Markarth mod and in uhm, another one I can't remember right now.
