I'll leave the event name and team number out but .......
I was having a number of typical issues with a team at an event (they were new to FIRST) and was working with them to get through those issues.
One of the issues was bumpers. They worked all day on practice day with some help from other teams to make a set of legal bumpers but had not yet put their team number on them. I told them to take them "home" overnight and paint their team number on on each bumper. Unfortunately they painted the wrong team number on them.
