To keep things short, I decompiled the game's files, debugged it, after 6 hours I got the crashing save/world to load, however a couple seconds later in-game, a memory corruption bug occurs that makes the game engine crash (bad memory address calculation, 0xc0000005 as the calculated address does not exist within the process's memory space) that can not easily be fixed without reverse engineering the entire game's engine code to find and fix the memory corruption (NOPing the crashing line stops the game from loading past main menu, NOPing the code after the game has loaded will result in a hang in just a few seconds as the game runs that code almost continuously with no corruption issues). Do not buy this, there are no patches and there will never be, noone is going to reverse engineer the entire game just to fix the crashing.
