This gets noticable in my game because people’s characters will have their legs stick through the bottom of cars and sit unusually low. I can trace this back to around the time when Rthro was added. But I didn’t notice this happened with non-Rthro characters too until now. The behaviour is still what it used to be with anchored seats.
Yes, I just tested again and the same issue is still there. If it’s to any help it can be reproduced by just inserting a Seat or VehicleSeat and setting Anchored to false.
We’re trying to get it out as soon as possible, but there have been some delays due to bugs found in the solution as well as changes in the release schedule due to upcoming holidays. I am hoping this code will be out before the end of the year.
If you are having issues with anchored seats in particular, you can temporarily create a script modify the HumanoidRootPart CFrame after the weld is created to lower it to match the seat. This is where the bug in the current code lies.
