Mild Act 2 Spoilers in tags.

Okay, so I'm in Act 2 and I've somehow gone from 1 Illithid power available, to 5, to 9 without knowing how I did it. Not sure if this is intended or not, it seems like a bug.

The only thing I can think of that might have added more Illithid power is
touching the illithid tendrils inside the wall at Moonrise Tower
. I think that's when I jumped from 1 to 5 available powers. But then I long rested and it doubled to 9 available.

I'm not sure if I have a save that's worth submitting to Larian, just wanted to ask if anyone else ran into this.
