Something is off with the triggering of the apocalypse, but once the effect has triggered it works appropriately. For example, when I deployed my 5th zombie it did not trigger. However, it triggered at the start of the next turn and displayed the updated status on my champions. It then continued to trigger (and place a new icon on my status bar, I had 3+ of them by the end every turn. A player told me that I could deploy a relic on my turn to force it to trigger, but I have not tested this yet.
