Sextant mod "cannot take reflected damage" is ignored by Boss Bodyguards

I experienced this two days ago when I noticed that my Totems died super fast during a map boss encounter and I think the only explanation would be that bodyguards ignore the anti reflect mod. I did not test this a second time.

So here is the setup:

I had two sextant mods
- cannot ignore reflected damage
- Unique Bosses are accompanied by Bodyguards
And I had a map with the Reflect Elemental Damage mod

My totems had no problem with the boss but i had to recast them permanantly when dealing with the bodyguards.
