[2020] Dreadful Apathy on Gods

I'm wondering if anyone can confirm a possible bug. It was my first sealed, so maybe I missed something else going on.

I played Dreadful Apathy on Erebos. I clicked the card to exile Erebos. I'm sure this went on the stack, because Arena autotapped the mana. In response, my opponent sacrificed creatures to lose devotion and make Erebos no longer a creature.

The enchantment fell off, and I thought this was a super clever play. Dreadful Apathy says it exiles a creature, there was no creature, so the trigger on the stack fizzled. But then I looked up the official ruling, and it says it should still exile the god if I'm understanding it correctly.

Is this a known bug? I'm willing to admit that I might have missed something else the opponent was doing (maybe sacrificing something triggered something else?). I was thinking about a lot of stuff at the time and reading my own cards to double check things.
