Found a mod to fix the V.A.T.S issue. Now V.A.T.S attacks (sneak) work fine. However the explosion effect is shown twise. Like one at the impact point and another explosion a little behind the above but with a slight delay (0.5 sec maybe?) Since it fixes the problem (although the shot would go through enemies much like AMR's bug), I'm keeping it and recommanding it for guys with energy weapon chars
