Please let the Sims move and live on the 64x64 lot.

Thank you so much for your answer. I didn't know you could change the lot type.
I want to change the 64x64 lot type of the Myshuno Meadows Center Park in San Myshuno.

Meanwhile I have changed other lot types just for testing. But this specific one I cannot change.

When I click in build mode on the I for Information it is not possible to change the lot type.
When I hover the mouse on Center Park it says "Für Spezialschauplätze deaktiviert". I guess this is translated "Disabled For Special Venues".

Can you please help me? What am I doing wrong?
Thank you so much in advance for your help!
