That improved the situation a little. Now we know the bullets aren't touching the tank in anyway. Great advice! But some still don't run their event function, which I know, because they don't "kick up dust" when hitting the ground. The majority of them do though. It seems this is happening only when particular parts of the terrain mesh are hit, which probably means your original diagnosis was correct.

But I had an idea. Since I did what you said and set the bullets and tank to the same phent group, does that mean I could do away with the c_move all together now? I know it's a fairly slow instruction, and it would be nice to eliminate. Hmmm... I could probably also start creating the bullets inside the actual barrel now too, huh?
