It's stated on the purchase page of the Official Server Host

Lan server over a virtual network like hamachi can just be janky and break but your cousin should also make sure hamachi can get through his firewall. If this doesn't work you might explore other virtual networks.

Sorry i'm not familiar with hosting Lan too well and I haven't used hamachi in awhile but you always used the hamachi ip and not the ip provided by the lan server?

They all burn for roughly 5 minutes, with a margin of of a +/- a few seconds. I just tested it.

Who hosts the the server and did you make sure since he factory reset hamachi was set back up correctly. I dont think the issue is on your part if the only variable to change is that your cousin factory reset but you were always hosting the lan.

Yes, delete the whole folder for that server.

Did you uninstall every mod in the ModsByServer subfolder for this particular server? Mods and server mods are independent.

Would love to see your list even if it is just a long list of bads. I think we could have a productive discussion on how items on the list could be fixed either currently in the settings, in the future by the developers, or by the good graces of a mod developer for items that dont fit into the other categories. You seem to be interested in making the game better otherwise you wouldn't of spent the time to rant your issues on the forums.

You will receive 4 keys if you already own the game. It's stated at the bottom of the family pack product information.
