@chrisbar_chirp this will be fixed in the next patch but for now you should be able to exit by using the hold-and-move method of control, or any of the joystick style control schemes
@xero328 @_3RD3M it happens when you use a tool and then click on the horse before the tool is finished. It should be fixed in the latest patch, are you absolutely sure you have it? (you can check by going to title screen, hitting the "?" button, look in the lower left, it should be build 34)
Latest mobile patch going out... at the same time as this, we're making headway on improving/fixing the UI scaling stuff. We're also aware of several other issues, so if you are still experiencing something, we are working as quick as possible to fix things & make improvements http://pbs.twimg.com/media/FmK9DhNaMAEhqIf.png
@lukard69 have you updated the app? This bug should've been fixed in build 34 (you can check what version you're on by tapping the ? button on title menu and looking in the bottom left).
@TomMoseley6 Are these the special order quests? It seems to be an issue currently with high resolution displays. We're working on a fix for it but in the meantime people have reported that if you put the items in the top row of your inventory you can donate them
