So I was playing an ability draft game earlier on today and I had chose overgrowth as my ultimate. After my blink I farmed an Ags scepter for the extra vision. Soon as I had it in my inventory my abiltys shrunk down slightly to try and fit the new ability on the bottom of the screen. Nothing else happened and even when trying to use the designated key for the new ability nothing happened. Even tho we did end up winning I did find it kind off annoying that I just wasted 4200 gold on basically a point booster and the equivalent of an ultimate orb. Here is an image of my hero after the purchase... . and the match ID 1350967278.
