I did get the same error message as the person in that thread. The server I was on in both instances is TNT-S8 Public. The server forum is https://explosivegaming.nl.

I just crashed, on the same server, again. It might be worth mentioning that I was in the blueprint library, looking through my own books, as well as that of other players, when both crashes occurred.

Done. I didn't see the Attachment tab at the bottom of the screen when I originally posted.

The game crashed in multiplayer. I was connected to a public server. I suspect the server didn't crash. I had issues connecting to some servers, when I first launched the game, which might be evident in the log, as well. I attached the log below. Enjoy!
