A picture speaks a thousand words as they say.  Playing Republique. When I hit the Z-52 I got two overpen ribbons and one penetration ribbon, so either one of two things happened:    One; I did full dmg and penetrated when that shouldn't be possible anymore (but I don't think this likely as that should give me 7,685, not 7,250 damage with 2 overpens + pen ) Two;  I got the bug where one shell 'penetrates' multiple times, in which case the actual pen was a module hit and did zero damage, meaning that two overpens did the damage value of five overpens, which is pretty fudged.    Either way, Wargaming, fix this.
