Since this has been going on since the game dropped I’ve come to the conclusion they simply can not fix it.
I’m sure there being an easy known work around did nothing to demotivate them to fix it.
The other one is push off ledges. We’ve had this bug since we could climb. Another one they apparently can’t fix.
The funny part is only NPCs fall through, not animals, why?
My opinion its a bad collision mesh that needs to be redone, but $$$$ so…
