Yesterday I encountered a problem where I was in POTD floors 51-60, as part of the normal grind most are familiar with. Anyways, we got two green-leafers that refused to advance to the next floor. When we asked them what they were doing, they said we shouldn't be rushing them, and therefore decided they wouldn't continue. After waiting another 5-ish minutes, we got impatient and booted one of them. We could not however, boot the other one - because now we had incurred "4 hour cooldown" from initiating boots.

So basically wasted our time there.
