I thought the developers might want to know this.
I wanted to attend the following party at around 11:40 AM EST:
I saw that only two people were in the room, so I clicked on CANCEL. However, I was not brought to the ship deck as usual. Although I wasn’t listed in the room list, I could still see the party room and people entering and greeting each other.
I thought I might just be invisible, so I tried to send a message. That didn’t work. I had to click a few times on GAMES MENU to leave the page.
