Did Double track end early?

As of prior to yesterday, I had several days left available to claim on the selectors yet when I went to claim it the double track was gone.

Check your STASH for any ones that were actually claimable (but not claimed yet).

That's where I was always claiming mine from each day, because game would always crash if I went into Double Track screen itself.

Yes, it ended.
