Joining match, confusing text.
This is less of a bug and more of a general, clarification that should be made. When joining a match in progress you may press "Use item." to que yourself to join. It changes the bottom text from:
Item - Join Game to Item - Cancel Join
New, particularly young or inexperienced gamers have a difficult time understanding, thinking they just canceled joining. Consider changing the text to:
Press Item to Join/Spectate Joining...
Press Item to Join/Spectate -Spectating-
This way the status is accurate to what is happening, not to what the next state is.
