Default Object Manager, what is it?

[Bashis]

this question is purely out of curiosity, as i like to know how things work. i was looking through tesVedit cleaning up some of my mod conflictions and i ran across a file header called Default Object Manager, the only things that have entries in that section are the official bethesda plugins and one armor mod i have, but the section is a total mess, loaded with conflictions and null references. now since only the beth plugins are using it im not going to mess with it, because cleaning bethesdas .esm files seems like a terrible idea, but im curious as to what this section actually is, and why its a clusterfuck of error
