Ohhhhhh looky here.... 


Also inside the file that makes a creation (which are .blueprint files), there are two types of positions variables. One position variable is for the position of the creation relative to the world. The other one is for each block and part, and this is relative to the center of the creation itself.
Now here's the bug. Apparently, If a part's, interactive's or consumable's (not blocks) position is set to 16384 or above - in others words, the 14th binary bit - It decides to not render the textures, making it invisible.
Not sure if that was interesting for you, but it was just something I wanted to show.
