Bugs found:

• Objects are moved to a far position when you just click on it (maybe there is a very little movement)
  How to reproduce:
  1. Click on the object that is added by yourself.
  2. Click on an SA original object.
  3. Press the escape key.
  4. Click on the object that is added by yourself again.
• Barriers like id 998 do not placing as what you see in the editor when you test the map.

Also, I think the output coordinates should be more precise. When I put some objects very close to each other but the textures aren't flickering, it does when I test it in game. At least 3 decimal places of precision is needed for those cases.
