6. I was disconnected from the server in the middle of a game, and once I reconnected, it showed me the game as if I were a spectator. I could still post in the chat, but I couldn't see my moves/Pokémon to select one. I tried reloading the page multiple times and it didn't help.
This game was the second time today that same error happened. Also, Opera is still crashing whenever I try to open Teambuilder.
Edit: The third time it happened, I copied the URL and successfully opened it in Chrome and selected my move, so it appears to be another problem with Opera.
