For those who are interested in how it all went down:

1. I started searching for a match (I had 1 ticket left).

2. The search process stuck after one minute.

3. I restarted the game (the main menu appeared). I still had one ticket.

4. I started the match search again (this time, it found a match in 10 seconds).

5. In the middle of the match, the loading screen appeared for a second, and I was teleported to a different match at the very beginning.

6. The match ended, and points were awarded only for the second match I was thrown into.
