[Whatever]

Describe the issue: Custom Props cannot be placed down on certain tiles. I do not know whether they are failing to be placed, or if they are being placed somewhere out of sight that even an admin cannot find them, but my livingroom remains unfurnished and my sprite wasted. This wounds me.
How to reproduce: Come to my house of horrors and try to place the coffeetable custom sprite seen in the provided image. It vanishes immediately. Yet, again, you can successfully place it on other tiles. (Keep in mind, I did a workaround by making a new custom prop with an extra long width to place it down on a 'working' tile.)
