I accidentally deleted a Process in Process Builder which was accepted in a previous step of the Lightning Experience Superbadge.  I am not able to move forward with the next steps.  I receive the following error message
Challenge Not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Delete failed. First exception on row 0 with id 0036A000001vfqGQAQ; first error: DELETE_FAILED, Your attempt to delete Sam the ninja could not be completed because it is associated with the following adventure packages.: null, null : []

What can I do to resolve this?

I have completed all of the steps for the lightning experience super badge, but when I submit the first quiz, it never fully processes.  I do not receive a score nor can I move on with checking the rest of the challenge.  Is there something I can do on my end to fix this or is this a system error?

I'm receiving the following error on challenge #6 of the Lightning Superbadge:

Looking at the Developer Console, it looks like the code which checks the system is forgetting to delete the Adventure Package records before deleting the Contact. Has anyone else run into this issue?

Thank you!
