Not sure if it's exactly bug or what...but I might bet that it's a bug.

After plundering, when you get this red circle, someone can attack you, and steals after being victorious...but what does he steals from you? For me it shows "...this person stole [3]" ..... what is that [3] ? coins? how much coins? I searched for a while on forums regarding 4.0 changes, or plundering in specific, I still haven't found an answer to it and I do not plan to waste any more time in search for nothingness.

So the first question 1# - what is that [3] ? supposedly bug?

2# If it's coins, how much coins you are loosing, was it like before - 50k per each attack?
