I have a new Giant; only level 10. She's still learning all the necessary skills. For a few weeks, I only logged onto her every day in order to collect the daily Advanced Play item.

Her stamina level is 1. She can't learn or achieve anything due to this low stamina. (Her other stats are 84 & 21.

What's the issue? Did I do something to cause this? I've got several other characters and have never encountered this problem.
