This bug has happened to me 3 times, out of me playing it 12 times.
But the 3 times it happened were not all in a row.
And other 9 times it didn't happen.
Thank you for bringing this to my attention, one last question though if you don't mind. Did it occur from the side where the door opened, the rear side, or both sides did it? I have been trying to replicate this, but I'm having no luck. I'm trying to do it in the build now, as it may have been a build issue and not an issue in the Unity editor.
Thank you again,
