This update adds the following.... 1. Fixes a major bug in the SA-15 Gauntlet missile code which was causing a major slow down when the missile was launched on the Norway map. Thanks to Stinger for finding it and providing detailed information on how to reproduce it. This fix will also improve performance on the Lush Desert map too but to a lesser effect. 2. Wingmen now have basic collision avoidance. They will detect obstacles in front of them and fly around, or over, to avoid them. 3. Guard towers at bases can now be blown up. I will be adding some physics simulation so they actually collapse in a later update. 4. Engine damage should now cause smoke trail at 75% health and then a fire trail at 50% health. 5. Fixed a bug that would cause some errors in the A.I. weapon selection system if you sent an "Attack My Target" command and the A.I. had a Sidearm equipped and the target did not have a turret system.
