Thanks for the report, denti!
Yes, you should be able to chain Sauna that you drew with Avanto (and vice versa).
In order to find out what happened (if it was a bug, if the interface was confusing, or there were other circumstances) it is extremely helpful if the game ID can be provided. All games are "saved" and can be replayed or reexamined later (like in chess, where a player may try something else in a game at a certain position where they later felt they played poorly). This also helps clarifying bugs, as in your case
The game ID (or game number) can be found at the start of the chat for the game and at the start of the game log.
I guess now it is too late for you to find the game ID (but if you find another bug later, please note down the game id of the game). If it was a rated game, there is a good chance to find it. For that I'd need your in-game account name (you can send it to me via personal message if you don't want it published here).
