"Chart has been removed because the field is no longer available on this project"

I removed a (n original, default) chart from a Dashboard and got this message, sitting right where the chart used to be. Yet…I did not remove any fields. What is this intended to convey?


Is there any chance someone else removed a field from this project @Stephanie_Oberg?

No, it is my personal project and I have sole access and have not removed any fields.

Also please note that the message was triggered by my removing a chart. A more logical message might be: “There is no chart here as you have just removed a default chart.” Nothing to do with fields, let alone field removal, that I can see.
