As the title says, I've got the data file configured, the groups show up in console when I type chat group list. However when I go to put myself in said group, I continue to recieve a group 'vip' doesnt exist. I've tried lowercase and caps. I cannot figure a way around this. Help please, thank you!

I am having the same problem here

Figured out mine, type chat group list and it will give you a list of your groups then you can change them. I had one captilized in the file but the command doesnt register it so i believe that was the issue.
