Sorry for my English!!
I have no time to read all the forum rules, please don't take me the wrong way, i just want to appoint this weird event for help the developers and players, and i don't know where to put the topic and I'm really short of time, so if its the wrong place, please move to the correct topic.
I only try it with the soviets
when we try to construct something the grayed form of the building appears to guide the player for where he wants to construct, well to me this appear but in a few seconds it disappear without my intervention. When i try to use an ability of a unit or from the tree happens the same with the cursor, it back to the arrow form for itself. I guess that's an error.
Thanks
