Hi ! I've been searching for answers to this and been looking through the settings for the mod. It seems like the only shells being able to penetrate other tanks are HEAT.
All types of AP shells never penetrate, frex a Panther or a Tiger shooting at an M3 from any angle. I only get non-penetrating hits with a "pen value" of 3, 6, 8 or 9 mm (depending on the gun).
So is this a bug or am I missing something obvious? Everything else functions perfectly fine. Thanks !
