Update app to fix bug

I have read most of the reviews and a lot of them are about getting certain characters that take a high amount of gems and when you send a character to do a task, it should take them 2 hours instead of 16 hours. I have sent a couple of my characters on tasks that say will take 2 hours but Ill check in a couple of hours, the time would be frozen and still have 2 hours left or so. Is there any way to fix this issue before Im having to delete it?
