Solved Direwolf20 1.0.3 server shutting down for no apparent reason

[mooop12]

As in the title. My server is a dedicated one, running Debian 7 with Java 8, here's the log:
http://pastebin.com/5aWwbEKd
As you can see it's spammed with "The world may have leaked". I found another topic about this problem from over a year ago and it seems it still hasn't been fixed. I put spot loaders in all the dimensions I know of but it doesn't seem to help. Those entries only show in logs, not in console, so I'm not sure if it was spamming it from the beginning or not, but it only just started shutting down the server today.

Anyone? I loaded all the worlds, there's only one left that's unloading now, with worldid -20, but I can't tp to it to place the spot loader, I get internal server error and when I reconnect I'm back at overworld spawn.

I managed to load the dimension with worldid -20 and now no worlds are leaking but the server still shuts down for no reason and the log doesn't help at all. Any ideas?

Okay, two things I've found out:
1). Crash logs aren't actually saved in the main log file in logs folder, they have their own separate folder called, you guessed it, crash-reports.
2). There's a bug with Witchery where if you try to disable hobgoblin spawning by changing "hobgoblinspawnweight" to 0 or less it will crash the server occasionally. Witchery changelog says the bug is fixed but the version where it's fixed isn't public yet I believe.
