Since the speedrun update, the entire thing has stopped working and I'm not sure why. I know a few other people I've told to have the same problem. The timer won't start when you deflect the first bullet.

If the problem started since the bugfix patch yesterday, it's fixed now

Still isn't working. Tried it this morning. I suspect it MIGHT be a setting but I'm not knowledgeable enough to figure it out. I know the basics so it must be an advanced option. But it's only doing it for Katana.
