:lady_beetle: Provide a clear description of the bug

I’m just setting up cursor for the first time and creating lots of MDC files as instructions for it. However, half my MDC files don’t load now and I don’t know why. If I close cursor and reopen, they will start opening again for a bit, and then stop.
