What's the biggest fix you've had to do in between matches?

[The Doctor]

Now that the regionals are coming to an end, I am curious, what are some of the biggest repairs you've undertaken in between matches?

In about 15 minutes:
Our team had to replace a round bar which was responsible for turning the ball intake wheels (after it got bent when 2013 ran into us). Immediately after, we had to replace the spring that powered our launcher, because the old one had become stretched and we couldn't shoot as far.
