Unexpected Wage increase bug?

I was in June 2012 trying to reduce my wage bill, rechecked my players and noticed that the wages of every player in my squad had increased by about 15% and none of my players had wage increase clauses . Reloading an earlier save didn't fix it but when I exited FM12 and restarted it, steam did some quick update of FM12 I reloaded my game and it was fixed, wages were back to normal . Anyone else had this happen?

Seems abit of funny one, cant say ive noticed but i know i few of my players had this yr wage rise
