I am having an issue where a chunk or reports have stopped working. I went to create an alternate version the sales order report, which I have done many times before. I downloaded the report, made the changes necessary, then saved the report under the new name and created the site map record. 

However, that report gave the error Nested reports cycle detected while trying to load, and trying to access the original sales order report gives the same error. It is also affecting all the other forms that are copies of that form. 

I’ve included a screenshot of the trace below.

If anyone has any advice I would really appreciate it!!
