Wonder Model in cities returns to "In Construction" state

I have had this problem even before any expansions have came out. Every time I start the game, the Great Library in the city returns back into its "In Constructing" state after I complete building it. I have also noticed it with Notre Dame. Currently, the only way to fix it is to save and reload the game, but that gets very annoying. Has someone else had this problem? Is there a way to fix it?
