Support request: can't re-run test that was copied from other location

Hi!

I was doing 3 references with 3 different users and moved the backstop_data to different location after each run. Then after changes on my website I switched 1 of them back. It does report of lot of changes in console but html report did show only 2 changes. Actually after checking further, I understood it was not generating the html report at all - I had deleted the html report folder but it's not coming back. So what is it missing? Does it need newer timestamps in the reference files? Does it have same hidden cache?
