Not sure if dysfunctional, but the Ectopic Adept has some strange wording. Its capstone and 3rd-level ability only function when you have as many craft (sculpting) ranks as manifester levels, which gets weird quickly.

"Hey, Bob the Ectopic Adept! Didn't you use to be able to create two astral constructs?"
"I did, but I forgot to take the mandatory pottery classes while fighting monsters in a dungeon, so I forgot how to do so."
"Then why does Fred the Ectopic Adept still has that ability? He hasn't expanded his pottery knowledge either."
"Yeah, but he decided to learn divine magic rather than expand his psionic powers: obviously creating more astral constructs is easier then."
