Unit models not centred to location?

[whyYOUmadSIR]

I noticed that if I apply effects to the location of certain units (priest, footman, spellbreaker etc), the effect does not align properly with the unit model -- usually looks to be shifted to the right. If I instead were to place the effect at the unit's origin as opposed to its location, it aligns perfectly. I would assume no difference between the unit's origin and its location, if the origin is placed at (0,0,0) in the model (which it effectively is for all of those units). Could you please give me a hint?

Picture is the "erroneous" footman with an offset rally point, and an archer with a perfectly centred rally point for reference. Rally points are applied to the unit's location.

It has to do with the unit's Collision Size.

Increase the Footman's collision size to 32 and you'll see it becomes centered again.

Thank you! Collision of 16-31 appears to de-centre it. It's a bit unfortunate since these would feel like the right collision values for some units.
