Bug Fixed: Fall Damage Bug
The fall damage bug has been fixed
"A bug came up ingame during the Scream Fortress update when valve tried fixing the Thermal Thruster. Each class is able to deal 3x falling damage (mantreads damage), thus dealing unintentional damage when landing.
We have decided internally that this bug will be legal for match play until it is fixed. It is too easy to accidentally deal falling damage while rocket jumping or sticky jumping, and the teams that do not know about this would be at an uneven playing field. Once this bug has been fixed, the use of fall damage will be illegal again. We won't be updating the whitelist to allow the Mantreads."
