Hey all, wanted to make a post here before I send a ticket to Zendesk to confirm this is a thing.
I have noticed that the Connection Lost error is a thing at the moment. Seen that the team is working on that.
Anyways, I was flying on Vatsim just now, and I had a sim crash. I saw that the screen froze while a Connection Reestablished error was visible (I’m not sure what the exact text was, but it’s something like that). After that, sim crash. I’m on version 1.13.16.0, Steam Version. I am running some addons, which could of course also be the issue of the CTD…
I can provide crash log, but I honestly have no idea where I’d find those 
Let me know if anyone else experiences this issue. Hopefully it will be fixed in the same hotfix as the one for the connection error.
