Also, wreckage, lostEco, and Bazaar may cause game crash if you have 2gb Ram. It is really should be fixed, because it is just unplayable. 40% of map not working. Lol.
Now I know why it is only happening on these maps. That's why. Thnx nepa. I had to clear my 8 GB RAM with a script in order to avoid more crashes. It was stuffed with Corel Painter and GIMP data :)
