Board Game Arena

I've been trying to start an async game with 2 of my friends. But they are a bit slow to accept the invitations and so the game expires and it's not there anymore by the time they see the message and have access to the table. Note that I have the game in 'training mode' because we are friends and no one cares how long the turns are. Is that why the game keeps timing out?

It would be nice if the invitations lasted a few hours so that my friends could get in the game.

Start the game as turn-based games and don't forget to 'open' the table.
