Lobby ID: 733107
Date & Time: 22 Jun 23:00 CET
This use-case:
1) I join lobby #1, it starts and I play it for a while
2) I add to a lobby #2 on the TF2C webpage
3) Lobby #2 starts
4) I report myself in lobby #1 and join #2
Although I should have cooldown after leaving lobby #1 I can still play lobby #2; if it lasts for 30 mins I don't have a cooldown at all.
I repped myself in lobby #733107, then I joined #733112.
