Doubtless as part of the V3 roll-out, Creatures doesn't initialize, or play. Both avatars are facing each other from a distance of a few feet, and the only way to escape the "game floor" is to concede... and if that doesn't work, the emergency exit is inacessible, so you're stuck.
I realize there are many things to be done, but just thought I'd drop a line, as I hadn't seen it mentionned elsewhere.
