I have reinstal Oblivion and after i install all official mod and oficial and unofficial pach. I open OBMM and start to think what mod i gona use wen i notice this Oblivion.esm[si] is not checked in mod list ?
I whas think that i uncheck him accidentally.
But problem is wen i test oblivion he ran whit no problem without this Oblivion.esm[si].
And wen i open Wrye Bash it say all mod i load need Oblivion.esm[si] because he is master, but agen i menage to ran oblivion whit no problems?
So is that Oblivion.esm[si] uncheck because of some pach official or unofficial or this have something whit obse loader or i accidentally disable him?

Oblivion.esm is always loaded as the first or "00" whenever Oblivion is run.
The reason why OBMM and Wyre Bash is saying that because it doesn't set Oblivion.esm as 00, thusly leaving it unchecked.

A word of advice to you:
Never load Oblivion.esm after any mod, this will cause everything to be overwritten (since it's the base game) and a lot of trouble.
