Artillery skill bug

Dark artillery shows the penetrate armor skill now. Since it's not mentioned in the patch notes I assume it's a bug. There was a similar one months ago when a troll had penetrate armor skill pop up too so maybe it's the same bug?

I noticed it too, light artillery showing this skill (in my case, cav in melee with elven ballista). So might be for all races.

A hidden change? A display bug?

Was a display bug back when it was with the troll so...

We found the root of the problem.

It is the "Misfire" effect, but with the wrong icon.

The correct icon will be added with the next update.
