That really sucks that you lost all of them. Sounds like the issues I was having with hatchrite last year. The babies were really messed up. No eyes or small eyes, kinks, some didn't have the end of their tails, and their bellies were split open. This year I went substrateless using the hatchrite and I'm on day 30 something and all my eggs are going strong. Last year I would have lost at least 2 by now maybe 3.
Granted I revamped everything for my incubator, but I'm thinking hatchrite was the main problem. Last year I didn't have any issues with temps and this year the power has gone out twice already and everything is still going well.
