I don't remember this happening in previous years, but it's done it to me twice so far and today I saw it do it to a random. Upon loading into the map, instead of each captain's name by their color you'll instead see a duplicate name of another player and as the TFO progresses it will display a mimic of their parts pickups as well:

The first time it happened to me I couldn't pick up any parts (the carrying parts icon/buff? never appeared over me), and it gave me an AFK penalty at the end. The second time I immediately quit and had to do it on another character, not sure if you can just keep trying in vain to collect things and not get AFK'd or whether you are forced to fail no matter what if this happens to you.

This is most definitely not a new problem and it seems one they are not interested in fixing given how many years it has been going on despite being report numerous times.
