Happened to me also, about approximately 2 hours ago, this happened, tried to refresh the page, relaunch Google Chrome, even tried to restart my PC and the problems still persists.

Might have happened because my laptop suddenly turned off due to a power failure while the tab was still open. Before that happened the resouces were tracked correctly.
