A lot of fixes have been made in the game over the past few days.
Last update includes:
-New buildings and trees management. This allows you to use up to 1GB of RAM less, and probably also have a more stable frame rate.
-Added many new props in Mission Editor.
-Added Smoke and Fire effects in Mission Editor.
-Fixed a bug where trees stopped rendering when exiting the Mission Editor Playtest.
-Now you can enter the LST in Kwajalein.
