Often when moving between a balcony and the inside of the second floor in houses you find yourself in the swimming animation. To try and get out of it you press V, but that also often sends you through the floor and you die.
This has been around for a long time, and using second floor doorway to balcony isnt such a great advantage as it should be.
Please look into this and get it fixed before rolling out the last patch.
