Unwanted transform group

I was modifying a rig. I made new legs, attached them to the root bone, somehow I got distracted and missed the fact that a transform group had been added between the legs and the root bone.

Now I don't mind getting a free independant hip rotator for free but its screwing up my game content export and I can't seem to get rid of it.

Thanks for your help

ok, so it's setup:
transform group >
+new legs
+root bone
??
not sure, but in any case you should be able to just drag your nodes around in the outliner till they are in the correct hiearchy. I might not be understanding it correctly, if not, give'm a little more info.
good luck!
