I am going to be quick in explaining this. My server was running fine, but when my computer blue-screened while it was running, it stopped working. Here is the log:
I figured that out, but what config file? What would cause it to crash?
What are the spigot-specific yml files? Where should I look?
Bingo. Spigot.yml is empty, how do I restore it?
Never mind, I just deleted it and ran the server again. Thanks for pointing this out to me!
