I just tried again, with 1 gk, 3 dc, 3 mc, 1 st.

of those 8, 3 had 2 sps while the rest had 1 each.

Of dispatching skill points in defense on those 8 players, 6 of them had the "handling" signed, the other one (mc) gained one in contrast, and the keeper gained heading.

Of the 3 with 2 skill points, one was the mc who gained contrast. Its second sp was signed as handling.

WHich make me thinks: could it be developments has fixed "growth"?
