It is how that spell works and according to Larians own description, it is intended to make NPCs hostile,when they realise,what happened.
So if you didn't had that before, it was a bug.
So you're telling me in 2 playthroughs, over 200h and using Friends literally EVERY SINGLE TIME it was available, it was bugged the entire time?
Because it has NEVER behaved like this for me.
