Simulated PHat makes character fall through floor (hair physics)

If I set the whole bones to Kinematic, except the hair/ponytail then the character will be stuck in place, can animate but is stuck in position.

If I set the whole physic bones to Simulated or default, the character just falls through the floor.

Any idea how this can be done without issues? I just want to simulate the hair bones :X

Never mind, it works now, could have been a capsule thing issue, but it didn’t work on my old project.
