Ok guys point taken.
My question still has not been answered, Its a simple question people which i will repeat.
When using MO and i select a mod to install, Some mods when installing say that
"It contains a BSA file, click yes to extract the BSA file or click no if you dont know anything about BSA files".
Thats my question and you all must have seen it pop up when installing some of the the STEP mods.
So is the answer yes or no???
I know how to use Wrye bash, Ive used it many times before, Im just asking is it needed as i always make a bash patch from good practice which can also be created using TES5EDIT.
