Allright, the server seems to be working.
I run it on my own PC, dedicated, so it can't be online all the time.
It should be in the server list under VineSauce CTF testserver
It's CTF and yes, Facing worlds, hall of giants, command, gauntlet and lavagiant should all be in rotation.
I don't know about Xui's lag, because for me he had a ping of 48.
