My timeout ropes used up by my opponent's actions
My opponent was running a Mill deck and I had Gaia's Blessings in my deck, so they kept stacking mill triggers and mill triggers. I click "resolve all", but while all the triggers are going, it's MY rope that's burning even though I clicked "resolve all" and it's THEIR triggers taking up all the time.
I just got timed out by my opponent's Goblins deck because my rope ran out while *their* sac triggers were on the stack. There wasn't even a button to continue so it wasn't waiting for me. Just using my rope.
