When the game launches the Halloween splash screen is shown. In world objects are using their Halloween textures, such as the ghost and tombstone.
Are you on the latest update V 2.4.18? We have a Christmas edition in the update and have replace the splash screen and removed the Halloween elements.
Please let me know if you are indeed on the latest version and the problem is still there.
I have the latest version, and the images for what needs to be “cleaned up” is still cauldrons, etc
