Game Mechanics: Charmed pet wouldn't respond to commands

[Irfzero]

I was in chardok and i had a chardoki golem pet. after a few charms he was down to about 5% health. Charm Broke. I messed him and then re-charmed him.

When my mes wore off he started fleeing as if he was low health - however He was still charmed. The pet did not respond to my pet commands and as he was walking(*Fleeing*) towards the first door in chardok about to train us - i tried rooting him. When i cast root, I got the message "a chardoki golem is protected". There was nothing i could do to use pet commands and/or spells on this NPC. It resulted in a subsequent train.

Has this ever happened to anyone else with charming a mob thats at low health?
