Root (Ancients)

I've built a unit that uses the Ancient Protector's "Root" ability. Everything about it works fine except: the unit completely loses collision when uprooted. It can walk through people and buildings.

Anyone know what's up?

(I've tried finding the answer, but the simple non-boolean searches on these forums bring up 13 pages of posts, many of which are poorly named. Nudge nudge.)

Maybe it has something with root working only for buildings. But your no-colission stuff is kinda interesting... does it make unit targetable or acting like locust?

Is it a hero and a building?

The unit is a non-hero structure. I've tried modeling it's stats after the Ancient Protector as much as possible, even giving it the Ancient classification.

I am going to try basing it on the Ancient Protector unit itself. Doing so may solve my problem, though it won't answer my question: what is going on?

EDIT: Oh, and Jacek, the unit is still targetable. It can just walk through things.

I just figured it out, so I'll answer my own question:

Don't forget, when giving a Root-using building movement speed and turn-rate, to change the movement type from NONE to FOOT, NovaBomb, you moron.
