I did.
As I said I've had this problem before; I just removed the Spellcaster trait and all was well.
I only have a bug this time cos I removed it and the problem is still there. She is no longer a hybrid, she is just a mermaid and she still can not turn back into a human.
(BTW I've just removed the mermaid trait then put it back on her and it worked, she is a normal mermaid, but I just thought you should know that removing one of the traits doesn't always work)
It was more of a statement that this is the only solution as far as I'm aware :D
It has been mentioned in this thread multiple times that it doesn't always work on the first try, sometimes you have to do it twice or choose a different path to remove.
