If I had to guess, Shadowkurse, it looks like you had a request to have your PTR account removed around the same time the original issue was being addressed. Unfortunately, the PTR, Beta and Stress test accounts look identical (since CS isn’t supposed to assist with any aspect of the Beta or Stress test ), so the Game Master that responded to your ticket removed the extra account they saw. It is likely that that account was the Stress Test license.
You specifically will want to submit a ticket and let them know that your Stress Test license was accidentally removed. They should be able to forward your account up to have it looked at. I can’t guarantee that they’ll be able to get it resolved today, but you should be set for future tests.
