Instead of when resolving the stack it should be when creating the stack, since being the active player that creates a stack of 600 triggers not only will it take a few minutes to load, during this time it consumes your timer. When resolving the stack there should be some form of safety net to prevent such things from occurring, however I dont particularly agree with stopping the clock as that would allow for heavy afk or idle abuse, as there is no report system that would be instantly taken advantage of.

Log:

Bump with a log showing my opponent reducing my clock over the course of three games even when I'm tapped out and can't respond to any of their triggers. In the last game I was down to a few minutes but still had time to attack for more or less lethal, but they cast some mill and edicts on me (that I could not respond or make choices to) and my clock timed out on their turn despite being 'F6d'.

Please fix the timer, it sucks.

What's more is that the player who owns the triggers will not lose time but their opponent will lose clock time even if they have auto resolved the triggers!
