That they take the contests down 10 seconds before gametime now? I have the join window up and the countdown is on, but as soon as it hits 10 (or maybe even 12), the contests all disappear, and if you try and join, they say the game has already started. You can’t do any last-second joins anymore. It sort of stinks for anyone watching for overlay because everyone is doing the same thing, but can’t fault the business practice I guess.
I believe you can still do edits right up until the last second, but I try not to put myself in that situation too often.
