It’s a unique item. You have it from a previous event, (so do I) once you get to level 2, which is when it’s unlocked, you’ll just need to spend 1080 on other stuff (walls, bats etc) to progress to level 3.
Does anyone know the max limit on making these? If there is one? I’ve been making them since the event and am at over 100 now and it’s still letting me make them. I kinda assumed there’d be a limit like the boardwalk tiles.
