Steps to Reproduce :

1. Install Discord Linker
2. Configure Discord Linker
3. use the command "stop" to stop the server (either side)

Description of issue : This doesn't Crash the server and everything is (seemingly) saved correctly. This exception is just some undesired behavior, that could possibly lead to more Problems over time.
