It sounds like there is something messed up with your disease data file in the data/Diseases/ directory. I haven't added proper error handling for loading custom diseases yet, so the syntax is very finicky. You can try removing your disease file from that directory and reload the plugin. If that works, then it means there is something wrong with your disease file (probably a misplaced character). If you post it here, I can help you debug the issue.

Thats the config or disease file corrupted.

i'd delete them & start again.

That newtonsoft Json parser library is really  badly error trapped.
