1) Go to the room
2) Break leg
3) ???
4) Profit
Joking aside I am guessing the leg break was simply the catalyst and that you are unable to crawl through whether your leg is broken or not. Obviously this is only an issue when you cannot move when crouched/standing and with the fracturing system seemingly delayed (I can only presume that was the reason for the broken leg) this problem has no arisen.
It's not an "urgent" problem in any way, in relation to some others, but it can render the player unable to play (or die at least for many in game hours) unless intervention is offered.
