Since about September 22, 2023, I got reports from friends that Roblox quietly rolled out a new collision update that made the lids of my trash cans very stiff, despite having nothing that actually clips or prevents the lid of the cart from swinging freely. Prior to this update, there was no problem with the lids opening. These lids are hinged via HingeConstraints, by the way.
You can even see the lid partially open, as if something was blocking it, but there’s absolutely nothing there.
I don’t know if this has anything to do with my trash carts being made prior to CSGv3. If anyone has been experiencing something similar, please tell me.
