Relocate is unable to relocate the tether'd necronomicon warriors or a dominated creep or Furion's trees,
it should be able to do so...


There is no such check in DotA to relocate only heroes... That is what Dota 2 currently does. Checks are:
- if the unit exists
- if the unit is alive
- if the unit is not a member of the player "Sentinel"
- if the unit is not a member of the player "Scourge"
- if the owner of the unit has not activated -disablehelp

The three units I have offered should be passing these checks.
Exact same check is done for back-relocating, too. Nothing more, nothing less.

The only thing that this secondary unit being a Hero changes is that; if the unit being relocated is a Hero, the camera shall get panned to the location of relocation. This is true for both the relocation and back-relocation.
