Hi team,
Server 30 just restarted mid-game while I was underway with my company, console says "Executing automatic server restart (no companies for 1 hour 0 minutes" and "The server closed the session"

yeah, there seem to be some issues with the servers since the upgrade to the newest version of OpenTTD

I will look into it!

It just happened again.

Maybe related: I logged in using the client fine, but minutes later another user came in and tried logging in (I saw the !login command in the chat), but there was no response from the server, so he didn't log in.

Here's a screengrab

I second this. I was in the same game.

Ok, got it… For now the best thing which I have in mind is to turn off the automatic restart of server 30 when there are no players.
This means though that a voterestart command lr a goalreached need to be achieved to restart a game, but lets give it a shot!

Will turn off the automatic restart now! Hope this helps!
