Told Minthara to wait, now I can't interact with her

I knocked Minthara out in act 1, siding with the grove to help them. When I went to Moonrise to help her in act 2, I told her to hide and wait. Now, whenever I come back to her, I can't actually speak to her and there seems to be no way to interact with her at all. Is there any known way to fix this, and has it happened to anyone else before?
