Glad you apparently got it sorted out.
Just wondering, if I am reading your problem description right, how did you get a project to use files from different audio pools (or what you say as "multiple locations)? Or even make a project using audio files from different audio pools?
I definitely understand how one massive audio pool for many projects can happen but, a project using audio from two (or more) different pools. That’s a new one for me. I would think this is not possible. If I am wrong, please let me know.
