Bug: Covers page sometimes links to wrong setlist
Sometimes the "Covers" page links to wrong setlists.
Example:
Viewing the page for covers played by NIrvana:
https://www.setlist.fm/stats/covers/nirvana-7bd69ee8.html
There is an entry for "Stevie Wonder" - i.e. Nirvana has played a Stevie Wonder cover.
However, it seems that sometimes the page finds the wrong show.
I have tried reloading the page a few times.
Sometimes it displayes the correct setlist, and sometimes the wrong setlist.
The following two screenshots are from the Nirvana covers page, but displaying two different results for the Stevie Wonder cover.
