I recently upgraded to 18.04.1 and am having trouble getting my Minecraft systemd service working again. I did a clean install of 18.04 from 16.04. This service was working properly on 16.04, but now it doesn't seem to work. When I run "systemctl start minecraft.service" it seems to run the ExecStart script and the ExecStop script together based on the status output below, but I do not see any output from the scripts in my tmux console that it should be running through. If I call the startup script manually, it works fine, so something is wrong in the systemd service.

The service is set to run as the minecraft user under minecraft group. Everything in /srv/minecraft is owned by minecraft user/group. The minecraft.service file is owned by root. All of this is the same as it was in 16.04 when it was working. Please let me know if you have any ideas to get it running again! Thanks!!
