Most people merged their leveled lists with Wrye Mash now or one of the command line ones floating around. I don't recall their names.
I see you joined yesterday.
Welcome to the forums!
Have a fishy stick!

I'll try to explain leveled lists and how mods can effect each other. If a mod changes one thing, and another mod changes the same thing, then the one with the later date on the .esp will win.
Leveled lists are randomized creature, loot, or npc lists (like the weapons on enemies or things you find in crates or creatures in the wild). If one mod edits one of those lists (like a creatures list) then only the last mod that edited that list will show in game.
You need to use a Leveled List merger to use all the changes together.
I hope that helped somewhat.
