CityVille: Sweeping inventory changes have users ready to quit

Zynga has made some... questionable changes to CityVille this week, that has many users virtually screaming at the developer, and quitting the game altogether. In addition to the new Energy cap that allows users to only hold 15 of each variety of Battery in their inventory, Zynga has also capped a number of other items to, as Zynga says, help the game's balance and introduce another element of strategy to the game.

The new caps concern items that are used most frequently in the game, so I suppose I can understand why users are crying foul.
Zoning Permits are now capped at 60, while Marble, City Seals, Building Grants, Gold Plating, and Ribbons are capped at 25. If you have more than this number of items in your inventory, you won't lose the extras, but you also won't be able to add anymore to your account until the number drops back below 25, or 60, depending on the item.

Another change worth noting is that you are now unable to user batteries from your inventory if your energy is at its maximum - it looks like energy stockpiling has been squashed in all forms, I'm afraid. If you try to accept a free gift from your friends, offering you one of these items, you will simply be told that you have too many, and that the item has not been added to your inventory.

This was enough to have users swamping the Feedback thread for this release over on the game's official forums, which has reached a whopping 173 pages in less than 24 hours.
