I have no problem with your new additions, though I do question your decision to remove the "rare" from "rare chance".
I have several hundred hours into this game, all played at 60fps. I have fallen through the floor while sliding down a ladder exactly once.
Maybe you're doing something I'm not that makes it more likely for you to encounter the bug. If so, it would be incredibly valuable to find out what you are doing to get the bug to happen.
