ServerJars could not be reached...

Attempting to load last working Jar.

All attempts to run failed...

Make sure that you're running a valid jar and version. You can use '--sj.debug' to find more information about this error.

And... i don't have a "cache" folder in this server folder, and don't have cached 1.12.2, this is strange
