I’m sure that’s the case (forward planning of goals), however they’ve shown that they can change things quickly if it suits them, ie recipes on previous goal appliances. In this case, all they would’ve had to change is a side goal recipe from one, to another, and the side goal cards to reflect that change.
It seems that there’s only a “rush” when it has the possibility of affecting them financially negatively, so I guess because some people may use their gems to purchase parts, it’s in their best interest to not fix it, hoping that those people might purchase gem packs (probably why they’re on sale at the moment!).
