What is the worst thing that...?

What is the worest thing that has happened during your build season?

Ours in order from worst too not as bad things that happened:

  1. Autonomous programmer didn’t get the code done soon enough.
  2. Having to redo a lot of the components(drive train)
  3. Some weight had to be removed
  4. Height limited our boundaries

Last 2 weren’t that bad but first 2 were annoying.
