Uhh, I don't for you people but I played some games with yetis since 2D and... they do less and less what I order them.

They easily go to "north" when you play light forces and when they have some issues finding a path.. 

And what is not so good too is that when I order them to attack something, they usually tell me back "Yeah, ok, but look there a little soldier, why not begin by what's just there".. it ok but.. sometimes they don't even move, just turning to begin to head to the target and just turn back to fight again against their first target..(and it's not that the target I assign was dead since it was a DG and he was still alive) It's annoying... so I try to talk to them behing my screen but nothing do ^^
