PLEASE FIX!!!!!

When Im walking in my map/place my screen will turn white and theres a cancel button and something will be loading and if I press cancel my character/person is stuck moving in the same direction I was last using and if I go to the screen with all of the options like the save and quit or settings and stuff like that none of those buttons will work so I have to exit the app and open it again so PLEASE FIX THIS BUG/PROBLEM!!!!!!!!

ALSO THE ONLY REASON IM GIVING IT FOUR STARS IS BECAUSE I LIKE THE GAME IN GENERAL.

(Sorry I had all caps on lol)
