After already completing first trip through each of the weekly challenges, I've encountered fatal bugs that make it impossible to pass the first stage.

Weekly endurance: the starting platform looses all collision after running forward. If you try to grapple, the line "cuts" the moment the character steps into the non-collision zone. Restarting doesn't help, there's no way to advance.

Weekly gauntlet: somewhere past the 2nd? checkpoint, one of the EMP platforms has zero collision. Sadly there's no way to advance without it, because it's a long forward series of platforms with nothing else to jump towards.

I can't figure out any way to fix this. Tried settings, tried restarts, nada.
