Upgrades missing

I stopped playing Chef Town for a while because of all the bugs. After a few updates, I decided to give it another try. Upon returning, I noticed that some of my upgrades are missing, which I used gems for. I had upgraded slots to receive 2 of the following items: water, vanilla, salmon, chicken, clams and/or crabs, sugar and upgraded slots to prepare 2 items in the cocoa/chocolate building and the pasta building. What happened? Also, ready items seem to disappear at random so it's hard to tell which plants, stoves, stands, etc are ready to be collected. Please compensate me for my missed upgrades.
