So I have run into one problem with current custom placeables. When you set a custom model on top of another custom model you cannot destroy it with a melee weapon, when you select bash it will say unable to reach. But when you set a custom model on one of the original models from nwn, it will allow you to destroy it. But you can still use and lock/unlock a custom model on top of another custom model. Just a wild guess, this is because of the way we make pwk's for custom models? maybe because there are 2 pwk's on top of each other? But I am not really sure.
