I only have one version of vehicles like EagleIV and MAN SX45, no weapons, no gunner, no control monitor, when creating a new scenery. The outside view (F8) don't show any weapons. By the downloaded "Tank Museum" made by Skybird, everything is working fine, two versions of Eagle IV, two MAN SX45 trucks. Piranha IIIC is the same problem, has no weapons, gunner, control monitor. ???
