Oh damnit, I didn't even see this. I'm sorry. So basically Evo is in a lobby crisis at the moment. Spring has always had the problem of Engine Developers/Game Developers/Lobby Developers
I am currently uploading a release to the github at the moment that will allow people to use https://springlobby.springrts.com/ (Springlobby) to play the game. I genuinely don't have a better way to do it at the moment. I am sorry. I am working on the issue. There is an all in one server/lobby/dedicated host package being worked on and it is super nice, but it isn't ready. Until then I legitimately don't have any better options.
I'll see if I can refund your donation. If I can't just let me know your paypal email and I'll send it back to you (I haven't looked at the dashboard yet).
Edit: Refunded it via paypal and disabled donations entirely (honestly I kinda completely forgot that they were still available).
