Problem on Sour Cream Street 3...

Is anyone else having the same problem that I am? Every time I upgrade the milk to cream station in the top right from a single pitcher to two, the upgrade reverses itself after a minute and I have to buy it again. Any thoughts?

I had the same problem on that level, and on another level as well (cheese street 2). It makes it virtually impossible to solve the level in time for 'gold'. I thought at first when I was on Sour Cream Street 3 that it might be a consequence of me clicking on the building too much, but then I played the level again and didn't click on it at all and it still happened. I replayed the level a couple of times until it just didn't do the reverse, I think it must be a glitch in the game.
