Today, I played QIWI TEAM PLAY DOTA 2 FAST CUP tournament(link: https://www.faceit.com/ru/dota2/tournament/4c0df34a-292e-4a83-87ac-c99e261caaeb)
This is link on match page: https://www.faceit.com/ru/dota2/room/c8f6a485-85e9-474e-825a-606ad87e5352
Players from opposite team used bug, when they could check in as opposite team, they wait for the end of timer and after this they go for their team and we had technical lose. And the button write to admine isn’t work!
