THe problem may have been due to processes running in the background, with a lot of iPhones and Android devices you can have a lot of processes running in the background and never really notice (Music, Facebook, Twitter)
While it may seem they are doing nothing these processes are still taking up a lot of Ram. It sounds like your phone is running out of Ram seeing Celtic Heroes taking up a lot of Ram and booting the process kicking you to the home screen to prevent your phone from crashing. That or has your device been jailbroken as this can have an adverse effect on the game.
I'm hoping you manage to get your problem fixed as it sounds more like a device issue, were you able to run Celtic Heroes on your iPad air 2?
Were other players getting disconnected at the same time as you? If so we might have to check server logs to see when.
As for your technical background concern I can very much guarantee you I have a technical background
