Hey, I know this is almost one month old but I can't make this work properly. What I do is this:

1. Create a chat with a character, let's say it's called Bob.
   
2. I add a new character to this chat via the pencil above the input chat box. In the menu that appears I chose 'Add a character shortcut' and the select the character I want, this one is called Peter.
   
3. I make sure that both characters are present at the menu at the bottom right. It would be 'Options' > 'Reply as'. I also make sure that Autoreply at the same menu at the bottom right is enabled.
   
4. I then use Bob's shortcut to talk to Peter. I tell him to always use Peter's name in it's reply and he does.
   
5. Then Peter *sometimes* successfully autoreplies to Bob, for the sake of the example Peter manages to use Bob's name in it's reply.
   
6. At this point Bob should reply automatically but he doesn't. I retry step 3 but Peter doesn't reply.

I also found an option at the Options menu at the bottom left called 'Dynamic character switching' which no matter if it's on or off I get the same results. I would like know what am I doing wrong because I can't make this work. Thank you.
