In another post I mentioned that there was a TB bug that gave it a lot of range. It happens because the hit box seems to move even when the character isn't moving. Resulting in the following GIFs in spoilers below. Note frame rate also effects the hit box. If you get a momentary freeze, (thanks to entry lag for instance), the hitbox will still move even when your player gets stuck during the freeze. Ever wonder why TB range seemed fishy sometimes? Here's your answer.
This one, could potentially be a big problem in OS now since the very attack that's bugged is the one people can chain infinitely now. Imagine someone trying to use this in St-2, it'd be hard to chase them because you'll get hit by that invisible range, which then they'll just move closer to the goal as you get staggered. Even if you take CS, they'll intentionally miss you and just keep heading for the goal anyway.
Edit: This may also be the same thing that happens with Katana charge.
