Generally it seems to be temp related.
82F is not too high but are you sure you didn't have a heat spike? Have you verified your thermometer is accurate?
Use as much incubating substrate as you can - it holds water which is an excellent thermal capacitor.
I personally have my incubator on a timer - it loses power at 10AM and doesn't turn back on until 10PM. The reason I do this is because as the room warms during the day, the incubator was coming on when the eggs were already warm enough - some thermostats really only work well when there is a decent difference between ambient temp of the room and target temp. So I really only heat during the night.
Also - on the really hot days, I put in ice packs - but not inside the tubs, just inside the incubator. That keeps the heat spikes at bay. Don't use too many ice packs though.
Also - if you are using a hovabator (what I use) - I keep the bottom plastic tray filled with water, and put the tubs on top of the metal screen. All that water in the bottom tray helps stabilize temperature to some extent. I've seen some people who just fill the bottom of the hovabator and don't use tubs - that may work, but I think tubs inside the hovabator are a better way. ----- I decided my old sig was too big.
