Funny, I originally did it as a server list but switched to a similar approach to the way that Paragon does it. That could be something I expand upon down the road as an update to the series as it would require a little more modifications to the existing system. Take a look at the Multiplayer Shoot project on the Learn Tab of the Launcher, though, it is set up similar to the tutorial series but uses a server list.
As for the crash, I’m not quite sure what’s going on from the logs, will need to confirm with the team around here.
