Recently / within the last one or two weeks while modifying reports, I have run into a bug where I'm modifying a calculated column and try to save the changes and I get an error saying
"Rename Column
The name 'X' is already used for a column the table 'y'. Choose a different name."
I'm modifying any column that already exists, so I cannot save any changes on that column.
Even worse: if I go to the formula for a calculated table, I try to change or leave the formula box without making any changes, and it gives me this same error about the table name, and it breaks the table completely. I have to quit the application and reopen from my last save.
This doesn't happen every time I open a report, thankfully, but it's happening to me maybe once every other day randomly - I haven't been able to figure out what specific set of circumstances is causing it to happen unfortunately.
