recently had a code that appeared on the buy-back screen for soldiers, probably should have taken a screenshot of it, but was in a hurry due to the war
the other guy attacked me, and went to buy back soldiers, and this was required to buy any soldiers
at the top was the number of soldiers to buy back
below it was like a CAPTCHA thing, it had the code printed right below where you put the code in
once the code was entered, it let me buy back my soldiers
it didnt really affect the war, it was kind of easy to do - but still, never seen that before
so what triggered it, and how can it be avoided? would have been an issue if the other guy was attacking me at the time
