I haven't installed the latest build on the stable machine, but if I remember correctly from the test machine, Studio packages are exported to the original package folder.
I never had any problems as described, but okay, I understand that it's a good design decision.
I always export these packages to the Desktop folder. Could it be added to to the export dialogue box to open the export folder after exporting the package? (Much like the Open folder button for export DOCX.)
