The Juneteenth Grill has multiple issues:
Says to complete it costs Zero gems regardless of how many parts are missing. Obviously can not complete for Zero, if you try it reverts back, but also means you can not choose to spend gems to complete.
If you try to use appliance parts gained from the cooking of recipes to complete the oven it subtracts instead of adding. I had more than completed the Yellow Water Balloons and was only short two Red Water Balloons (Spent $4.99 for 10 of each part, rest were gifts or responses from neighbors). I tried to use the ones we get from completing recipes to finish the Grill and now only have 8 Yellow Water Balloons and 24 Red Water Balloons.
Can you please credit me back the parts that were subtracted? So frustrating that I spent real money and now am further behind.
