In the first game you play with the guys, if you select to tell Yuugo for your question "You've switched sexes for a day! What do you do?" in the chat when you send it to him it just has the "You've switched sexes for a day!" but it does have the other part when he presents it to the rest of the group.
Also, I believe this one is already kind of in the 'Known bugs' log, but in Yuugo's route when loading a save in the chat that happens after a particular server notification on Day 8 (or is it 9? I don't quite remember, haven't had much sleep and I lose track of the days in-game anyways ^_^;) it displays that chat and shows that your character is typing, but never moves past that. If I load before that in a chat, it has the bug of showing that your character is typing but never moving past it. I took a screenshot of the Yuugo route specific bug, but I won't post it here so no spoilers ^_^
