Just played a game - my opponent went infinite with Scurry Oak + Heliod, Sun-Crowned + Soul Warden - or rather, as infinite as you can get on Arena. They persisted with the combo until they used up all their timers. The thing is, I had been auto-passing this whole time. Yet, for some reason, after they used all their timers and their triggers started auto resolving, MY TIMERS STARTED GETTING CONSUMED TO THE POINT OF EXHAUSTION.

An issue for multiple reasons:
1. I was also playing a combo deck, so I needed those banked for my go-off turn.
2. For whatever reason, once done, it allowed them to attack without issue, but did not allow me to block. So despite two blockers and their attacker having no evasion, the game was over.

Extremely infuriating as I legitimately had a 33% chance to win that game if I could block then cast my end of turn instant. I sincerely hope the opponent didn't know it worked like that because then they're absolutely abusing the bug/issue.
