playground=swing
Is it fixed as above?
Please confirm if you can.
Sorry if I made any mistakes since it's been a while since I edited.

Hello ateusz Konieczny.
I believe this was a mistake I made when I was still new to map editing.
playground=swing
Since it's a swing set, I think your answer is correct.
I edited this quite a while ago and have since forgotten how to use the editor. I'd like to correct it once I remember, but if you'd prefer, ateusz Konieczny, you're welcome to make the correction yourself.
Thank you for your help.
