I just had a similar issue in the myconid circle, but I'm not sure if it's a bug or deliberate. Just got the first big illithid parasite power and am playing a druid, so it's transforming into an intellect devourer. If I do it, they all aggro on me after a few seconds. Even the deep rothe started attacking me...
That is intentional im affraid.
Or at least it makes sense to me that when you asume form of spmething that is hated and feared by everyone ... they will hate and fear you aswell.
