Today while I was editing my lineup, I had multiple occurrences where I was redirected to the "something went wrong" error page and lost all of my unsaved edits to the lineup. There was an auction finishing for a staff member I had bookmarked, and from what I can tell the refreshes appeared to be caused by the Active Bids panel trying to update the current status of the auction (the auction was in extended time due to last minute bidding).
This occurred on Windows 10, Chrome latest.
