The pieces of the WitTwo's corners aren't really held together that well, they like to pop out every once and a while for me, and it's pretty annoying to get them back in.
Happened to me earlier today as well. If that happened in a competition, would you need to put it back in for it to be considered solved? It isn't a functional part of a cube, so you shouldn't need to.
