I don't know what it is, but somehow the devs manage a way to learn my work schedule to the hour, and plan the end of the test for right in the middle of something I have to do. It's pretty sneaky, but I have to admire their consistency.
So I feel sort of out of the loop with the whole end-of-test party thing. What is it? What happens? Is it a dev-backed thing? I hear lots of ridiculous stories about random things happening and it sounds like a lot of fun.
