I've updated to 1.2 and for some reason the physics behind bdarmory have changed, back in 1.1 they seemed to work fine. I'm having issues with KSP/squad parts not absorbing damage properly. I built a tank out of structural panels and changed the file on the structural panels to have a higher damage protection rating. The problem is, bd armory is shooting (even with very weak guns) straight through the structural panels and completely killing the inside of the tank with 1 shot while leaving the outside in slightly damaged condition. This was never an issue in previous versions, the other versions seemed much more realistic.
