Is there away to tell which climber has already placed their tent? In a recent game, one of my climbers got in a trouble because I was going to place a tent, but got the message this climber has already placed their tent. Is this there something I am missing where you can tell if a climber still has a tent available?

There is a smooth climber and a lumpy climber on each team. Each of them has a tent, and the tents are also smooth and lumpy. If you look at the map and see your lumpy tent is already down, then your lumpy climber doesn't have another tent to use.
