When launching Server in Eclipse, this pops after:

 

[18:13:24] [server thread/INFO] [net.minecraft.server.dedicated.DedicatedServer]: Done (0,935s)! For help, type "help" or "?"

 

It appeared just today in my dev env., now - I know what that is, but I have no idea why it exist.

I am not having ANY problems with connections (but this ofc.)

 

I literally did nothing, it just appeared (same code, same everything).

 

My guess would be some VersionCheck in forge, but I just can't get over it without knowing why ;p So annoying
