And it's my own fault.
Forgot to specify output folder after creating a new project. It put the file in the folder I last specified for the previous project, and I forgot what that was, so I had to go find it (it was apparent next time I went to export).
A long time ago we discussed making the DEFAULT destination folder for exports to be the PROJECT FOLDER, not last used folder.
Should have a settings switch to choose project folder or last used.
Anything happening with that?
