When I upgrade a critter using the traitstones some of the traitstones required for the next upgrade vanish. Not the ones consumed - the entire class of stone. Here are before and after pics. Could somebody explain what’s going on? before upgrade ![before](https://us1.discourse-cdn.com/flex019/uploads/gemsofwar/original/3X/4/b/4bccbce4709431bb1b2111fa66207847c4d5bb90.jpeg) after upgrade ![after](https://us1.discourse-cdn.com/flex019/uploads/gemsofwar/original/3X/1/7/17c67d910550dcdd63ea531b6139b653ae9cafd1.jpeg) ---

It’s adding them up. In your first picture, the traitstones required for trait 3 are what you need to get all of the traits, so 1 ,2 and 3. In the second picture, you already have trait 1, so the traitstones required for trait 3 are those you need for trait 2 and 3. ---
