1. Walking out of the room for 3 minutes, a popup had come up asking me to click.
2. Hitting 'refresh'
3. Closing the window behind the training module.
4. Logging into CCS, and then clicking over to another instance of SkyNet to check flights for my wife.


Each one of these erased all my progress, with two of them letting me complete the activity before not giving me credit.

Anyone else have similar war stories?
