Move unit to "Position of Unit" - exactly! How?

Anyone know how to move a unit to the exact position of another unit? I have collision turned off for the destination unit, and the other unit even has movement type set to "FLY". But it still ends up being outside the destination unit's collision radius (which I need to keep).

Edit: Hmmm nvm the math - distance between points is ZERO which means the model isn't centered properly or something (glowing rune).

Check if the distance between your targets is less than or equal to the offset you use and then disable the trigger.
