Problem with foliage when sculpting

Hello,

When sculpting foliage it does not follow landscape anymore. It used to work fine before.

If i add more grass / trees then those follow newly sculpted areas but not the old ones. Anyone have an idea how to fix that problem ? I have tried reapplying settings, world collision, align normal etc
At worst case scenario i have to start deleting foliage and re applying. Any help appreciated.

Old post, but the answer is to untick Align To Normal on the specific grass in question. Only Answering this, so it helps someone else. No one ever seems to answer these questions.
