Invisible Items
Can you place anything where they were?
Yes - This could be down to a Rollback. Alternatively you may have stored them by mistake (We've all done it!).
Check your storage buildings and if it's still missing, Contact Zynga.
No - The item is stil there, but invisible. Usually this is a short term loading problem and can be helped along by clearing your caches. Most of the time the issue will fix itself before long.

Please remember we're not Zynga, these are simply steps we've devised over the months of playing that may help solve some of the in game issues.
