To cure the problem inflate the balls with Helium instead of air and they won’t deflate or inflate with temperature change like they do with air.

I wouldn’t go with helium simply because it defuses through rubber faster than any other gas. Use Nitrogen. That would be fine...
BTW, if they had been inflated with CO2 instead of air, you might well have seen that big of a pressure drop at 45 degrees. For that matter, the pressure drop in CO2 from 70 degrees to 45 degrees pretty much matches up with the pressure drop in the balls. Being as though it’s the cheapest and easiest compressed gas to get, it wouldn’t surprise me if this was what happened. Also, by having a CO2 tank and a regulator, this would mean the team would not have to lug around a compressor.
The only problem was that they should have chosen Nitrogen instead, but they wouldn’t have known that...
