Of course I've been up all night! Not because of caffeine, it was insomnia. I couldn't stop thinking about coffee.
Thanks. Also can we play more than one event at a time?
If you mean simultaneously, then no. If you mean during the same window of time, then yes. Play an event, resolve it's effects. Then play another event. You can play as many as you can afford as long as you are allowed to play events (see timing diagram). However, you play them one at a time.
