Taking over a zone

I attacked from Peru to argentina with 1 soldier (am I even allowed to do that?) and won, now it shows 1 on Peru and Argentina which is 1 more soldier than I should have.

What browser are you using?

You had 1 Soldier on Peru and attacked to Argentina? Then magically another Soldier appeared on Argentina?

If you had 2 troops on Peru and attacked Argentina then you would roll 1 die and when you won it would skip the assault transfer stage and the territory would immediately be yours, having that 1 troop on it. Are you sure you didn't have 2 troops on Peru?

I am positive I did not have 2 troops on Peru.
