Hello there.
I've been messing around in 3Den (which is a fantastic tool by the way), and, while creating a quick offroad chase (with the new shooting position), I've realised that, when one fires an RPG, it would occasionally blow up the shooter.
This has happened on several occasions (2 times out of 15 I would say).
Yet, I have not been able to pinpoint its cause. Each time, the offroad, driven by an AI, was going at medium speed (about 60-70 km/h).
