The devs broke the log. It no longer shows player join/leave properly. It just has ??? for most values. This can't be fixed, but the join regex can be. They added a space before the line previously, now they added one after the line. I'm adding buffers to each line as a failsafe.
During the Proton feature enhancement I accidentally removed the Steam SDK update stage. This should resolve it so players can view their server in the browser again.
This switches the config to use a base config rather than a template to allow users to manually add special settings without a full config file overwrite.
