2. I can no longer get in because of mods. It says "Check if the server has the latest mod version installed".

Please proceed as follows:

1st step: Please check if you have installed all mods from our cluster!
https://steamcommunity.com/sharedfiles/filedetails/?id=2396667183

2nd step: Close Steam: Restart Steam after a few seconds, a download should start. If this is not the case,
go to step 3.

3rd step: Deactivate and activate mods: Go to the workshop, see which mod is the last updated, click on it, unsubscribe it.
(evtl briefly wait for the 0kb download) and subscribe to the mod again! A download should start.
