I know it should not be happening, that is why I am reporting it.
I was playing the "Golzow" scenario (EFOW) against the allied AI and guess what:
My king tiger managed to shoot a IS-2 that was behind a building! The line of sight before the shoot was going throught the very middle of the structure-actually the diagonal cutting the house from corner to corner. (of course the IS should not be visible to my tiger at all). I know that TIGERS were super tanks, but this goes too far:)
NOTE: I dont know if this is of any improtance to the game desiners, but may be I sould mention this particular house was in a oblique position in relation to the horizon (which is usually an exception)
