PROJECTILE TIMED
If projectile is flagged as an RPG projectile, then this flag will make the projectile disappear.
You have to define the projectile with PROJ_RANGE. 30 units = 1 second. Which is the ammount of time before the projectile will disappear. Keep in mind. If this flag is set, the projectile won't start the spawn option, sound options, and probably a few more options.
