So the chickens I have laid 2 eggs. The first egg was a success while the second one was a failure. But when I looked down it isn't one chicken that spawned, it was four.

We currently have witcher-3-blood-and-wine and witcher-3-hearts-of-stone which are DLCs for the-witcher-3, so shouldn't they be renamed the-witcher-3-blood-and-wine and the-witcher-3-hearts-of-stone to fit the actual game's name?
