Trying to update a self hosted Vintage story Server from version 1.20.12 to version 1.21.1 Can anyone give some advice or helpful instructions in how to update a server in general to a newer version? Do I need to fully replace all files in in server folder with the ones i downloaded from vs_server_win-x64_1.21.1? or do I just replace certain files and folders for example?
