[] Poseidon achievements dont unlock

No matter how I ride the rollercoaster, it never counts for the achievements

Steps to Reproduce

I have tried with and without jet pack equipped; I have tried front of the ride and the back; I have tried with an empty equipment bar. I have tried front and back. I have tried workshop-model, skeleton and milk carton. still nothing. It never counts

What I expected to happen

after 1 full round (getting on @ the gates), I expect the achievement to pop when the coaster comes to a full stop/I can get off again(the sides go down)

What happened

nothing happens and riding the coaster was not counted at all.

Notes / Media

It seems that setting model to the girl did allow it to count. May wanna check if the bug is model-specific or not.
