I'm in the early stages of setting up a scene with three characters, and while I can use the gizmo to rotate two of them around their own axis, the third rotates around another character's axis. Does anybody know what might be causing this, and how it might be fixed? She's not linked or parented to anything else, so far as I can see. It's very annoying.

UPDATE
OK, I seem to have solved the problem by clicking on something that returned her to the original "T" position, but could not figure out how to replicate that in order to explain more clearly what i did. Nevertheless it's not a problem presently.
