- Fixed various methods players used to escape spawn during the 10-second countdown
- Fixed broken countdown screen state when a player would abandon the game during the final countdown

Rumor has it:

- Remember that pressing F7 allowed you to file a report? You no longer need to memorize that key, [url=https://www.reddit.com/r/tf2/comments/49wniq/new_ui_and_report_interface/]as syberspace_ of reddit points out a button for reporting players has been added to the menu[/url] while in a game (including outside of competitive)
- As it stands, the prompt seems to be quite bare in comparison to the prompt brought up on pressing F7: [img]http://i.imgur.com/D0DfaUV.png[/img]
- Four options exist at the moment, these are "cheating", "idle/AFK", "harassment", and "griefing"
- Unintended side effect: you can also try to get yourself VACcinated if you want to, as demonstrated in the above image

- As you might expect, an item schema update: [url]http://git.optf2.com/schema-tracking/commit/?id=cf50d2792576b1477424cfe63d14266d8278a114&context=10[/url]
