With DiscordConnect installed and the bot active the server hangs on shutdowns/restarts reporting:

02.07 15:52:10 [Server] Server thread/INFO ThreadedAnvilChunkStorage (DIM1): All chunks are saved
02.07 15:55:04 [Multicraft] Terminating server via signal
02.07 15:55:05 [Multicraft] Server shut down (terminating)
02.07 15:55:05 [Multicraft] Looks like a crash, check the server console. Return value: 143
02.07 15:55:05 [Multicraft] Server stopped

Fresh server log before restart:

the server doesn't generate a crash report.
Problem clears up when discord connect is removed
