I don't know if I am missing something obvious, and if so, sorry! Reopening the project file in PAT 1.14.0 deletes the old results. The previous version didn't have this problem. I also noticed that all the design alternatives in the PAT folder also get erased. I am still able to export an XML report to see the old results, but none of the individual folders for each of the alternative runs("data points") are preserved in the folder. My colleague encountered the same problem on a diferent PAT project as well. Has anyone else encountered the same problem, or know how to preserve results on closing the PAT project, and reopening it? Thanks in advance!
