Many people are unaware that several problems encountered within the game, can be solved by clearing the Farm Town Memcache. This is extremely easy to do, and takes less than a minute. All you need to do, is click on the link below (making sure you are not on your farm). Another page will open up, and it will be full of writing.
Just close this page down again, and that is all there is to it.
Your memcache will now have been cleared. You are now free to see if it has helped to solve your problem.
