So I fight the merrca bros and I win. I try going to healing spring, and then i get "No way!!! - Trying to get healing while in a battle eh? Come back later!". I already beat them, so I was confused. I go back to the battledome and it straight away starts another battle with them. I win again. THen go back to Healing Springs, I then get "No way!!! - Trying to get healing while in a battle eh? Come back later!". So on the 3rd time I draw with them and am out of HP. I go to healing springs and get "No way!!! - Trying to get healing while in a battle eh? Come back later!". What do I do? Its on a constant loop....
After you are presented with the 3 choices (Play Again, New Challenger, Quit?), stop there. Don't touch anything and open a new tab to go the Springs.
-OR-
Click the "Challenges" Button at the top of the BD interface when you're not in a battle. It should be empty. Sometimes it's buggy or lags, so you're caught in a battle you didn't know you were in. If you have a challenge, finish it, then refer to the first 2 steps I mentioned.
