Rather odd tubeless issue!

Has anyone else experienced this issue? I've had a set of Bontrager tyres set up tubeless with Stans sealant for >1 year with no issues at all. This weekend I put the bike in the car on the Friday night to go for a weekend away. By the Sunday both tyres are as flat as a pancake. No obvious sealant leaks and still about 30ml sealant in both tyre.

It was very hot in the car, probably >50 degrees C in the full sun when parked up - could this be the issue? Now I'm home I've pumped them both up and they seem to be holding air again.

Very odd!
