I had a backup (of some kind) ready to go as this was an issue to be predicted. It got all channels, roles and more already set up at https://discord.gg/G4k3hW4
For now we will be using that one (Talked with Riylan about this)
The owner of the old Domination Earth discord server quit the game several months ago. He said he'd leave it up running though. I'm guessing he didn't want it hanging around anymore. Sadly he did not give any of us any warning.
We apologise for the hassle right now.
