I opened the June 10th 'Final Fantasy is on Arena' announcement and got the 3 packs but not any of the fullsize basic lands. I already had 12 out of the 15. I assume the game rolls 1 in 3 on each basic land and then there would be a 30% chance I got no missing ones. That's fine but I didn't see the animation from obtaining the lands like I did for all the other new set messages that gave 3 packs and basic lands.

I'd like to know if Arena is working as intended and I was just unlucky on not obtaining a missing land.
