What happened in Curie Finals 1 (2013)?

I was watching the match video, and I don’t know why red got zero points in that match. The score display shows that blue got 20 climb points and -20 disc points, for a total of zero, even though blue probably had close to 100 disc points.

Does anybody know what happened in this match?

1918 fell off the tower and the red alliance was red carded for knocking them off.

The call was wrong, even if a red alliance robot touched 1918 during the climb, they did not cause the fall. Both alliances protested the call together, but it didn’t matter.

Either way red won the division in 3 matches.
