Blockland stops working after exiting my own non-dedicated server

[JPSC]

When I exit my own non-dedicated server, Blockland freezes.
I have uploaded a console log of me starting a server, loading a default save and then clicking "Disconnect".

I'm not sure which mod it is, but one of your add-ons is causing the problem. Please try starting a server with default add-ons and see if the problem continues.
