As you can see, I first moved one tiger next to the T34 and checked projected casualties: 4 0+
I move the second tiger and again check projected casualties with the same tiger as in step 1. The expected result would be either 4 0+ (no difference) or 4 0 (slight improvement) as Panzerkeil should raise the defense values of the tiger. But...
The projected casualties are now 3+ 0+. As in, either the attack value of the tiger has fallen or the defense value of the defender has increased. One suspects it is the latter and the panzerkeil bonus to defense is being incorrectly applied to the defending tank rather than the attacking tank. OOPS. Please to be fixing?
