We, uh, don't! That sounds like a bug that I would love to slay. Can you give me some more info?
But it should only take one screenshot every 30 seconds, and only when something changes, so this is a bug! I will fix. Thanks so much!
The bug is in my reporting tool I just realized. Yes, it reports only each time the screen change. Sorry about that. About multiplayer, understood, make sense.
