Turns out I have to visit my folks this weekend, so I am unable to play HWK or Insurgency.
I contacted Mojang again (still no answer, and the password reset does not send me anything) and got this notice:
"We've got a bit of an email backlog at this time. As of September 15th, we are answering emails from August 19th, and are currently in the process of training additional support staff. Thank you for your patience; we look forward to helping you soon."
This means I would not be able to chill on my own MC server for a while.
