Game slowing down

What you were expecting to happen, and what actually happened?
After doing multiple challenges or treasure hunts in a row the game slows down significantly, and the more i play them the slower it gets. Problem removes it self away after I restart the game. This slow doesn’t occur when doing multiple PvP battles in a row. Why is the game slowing so much? I have a very strong phone, it runs any game on play store without a problem. .

What are the steps to make it happen again?
Well do it yourself, don’t know if others have the same problem as me.

Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
Screen shots would have no use.

Gotta Love memory leak

Same here. On latest Android build (using a Nexus 5)

Still with 1.5 GB of RAM it shouldn’t be a problem. .
