Hello, I'm rather new to OpenRCT, I've noticed the limit on objects and a workaround (I think?) to use all objects in the game. Although I'm reading that only objects/attractions that haven't been build can be disabled. Nevertheless I'm able to disable attractions that I've build, and pick a new one which comes available in the attractions tab. My old attraction that has been disabled, is still in the world functioning but obviously I'm not able to build it again since it's gone from the attractions tab. Is this working as intended? Or am I missing something here? Because isn't this a workaround for the limit? Thanks.
