In case u have her on the highest affinity level (not romanced) and want to use her further, don't dumb or switch her, otherwise u won't be able to take her with u again.
Her dialog gets stuck and whenever u talk to her u get to choose between 4 answers, all over again.
Just had to throw away 5 hours of gameplay cause of that.
Not even possible to access her inventory anymore (once the player sends her away).
