Lucas Oil Stadium in Indianapolis was a little chilly during the Colts game on Sunday…and that was still the case Monday morning.

Half of the stadium’s roof was stuck open during the second half. Shortly after the game, another attempt at closing the roof also failed.

Officials told the Indy Star a sensor in the west side of the roof is malfunctioning, which prompted them to wait for daylight to try again.

The stadium opened in 2008 at a cost of $720 million, at least $620 million of which came from taxpayers. And this isn’t the first problem the roof has had. A bolt fell and injured fans in 2015.

The latest problem spawned a number of jokes about the stadium, like the team, failing to close out the second half of a game.
