Update #31 patch #4

This small patch fixes a couple of issues.

• fixed reloading a savefile resetting the game edition buffer, resulting in being able to save & reload after sales to get the initial sale buffer counter back to 10,000, effectively avoiding having to pay for manufacturing new game edition copies - fixed a crash that occured when attempting to sell a door after cancelling moving it - fixed a potential issue with losing track of related games after loading in some strange cases, resulting in crashes - the quadtree optimization in Update #31 Patch #3 was reverted due to being unstable; the issues in the optimization have since been fixed, the optimization is now present in the game, and provides an even bigger performance boost than before
