Eh – Clash of Clans Review

It is a great game except for the fact that when I upgrade some things, I will leave the game to do something else and when I go back into it, the upgrade doesn't register and I have to upgrade it again. I do get my gold and elixir back but it is very time consuming especially on the higher town hall levels. If anyone knows a fix please help me!
