Twilight Suzuka, i did that using ur ArrayX plugin, but i haven't really tested it, kinda stopped running a server. I'm now thinking i change it to nvault. You took over entmoving anyway (well not really, but u said u did), so i guess it doesn't really matter
atomic copying a ladder is possible, the part you actually climb is called func_ladder. When you just copy the model thats on top of func_ladder, there is just nothing for you to climb
