This glitch comes into play with Sandbox+ You have to do a command to load a chunk swap and then weirdness will ensue. To start, type 888 215. Then do 888 144. IF you start falling through the floor you know you did it. If it didnt make you fall through the ground then do 888 215 again. Now some areas will make you go through the map infinitely. Your game is also prone to crashing at this point. The most interesting thing this glitch can bring is, failed loading of districts. Instead of the game rendering, sections of each district will have their distant lod texture there, which is a low poly version only usually seen at long distance.
