I know I just saw something about this recently, but I can't seem to search intelligently enough to zero in on what I need.

I have a project that generates fine in BIAB. I save the MGU file, and open it in RB.

Drums do not generate, and I get an error saying that the directory RB expects to find them in does not exist.

I thought I saw an explanation of how to edit something that has some real drums in the wrong place making RB unable to find them. If anybody finds it before I do, please holler at me. Thanks.

Meanwhile, I'll keep looking...

update...
I can't get ANY drums to generate!
