I suppose arty need to be driven outside of all base circles to be able to shoot. But zamak MRL can shoot while still inside outer circle. No sure how it goes with sandstorm. Is this planned behavior with zamak MRL or bug?
Found the bug and fixed it for the dev version (the one with other fixes so stay tuned) (was a small unwariness in the class names, we were looking for MLRS but the Indie one is just MLR, so it didnt recognize it as a MLRS)
