As an additional note, I tried entweing the IP minus the port number and quick clicking Crasite but it still didn't work, Crasite didn't show up at all. However, instead of trying to locate the server through the steam menu I launched Ark separately and that made Crasite show up on the game's server list. This time, anyway. If it turns out to work consistently I'll post my findings.
