What is the expected output? What do you see instead?

Please provide any additional information below.

Do you remember if some raid group was empty when you joined the raid ?

Update: Uploaded a new version that must fix this issue (i wish).

I think I probably was probably added to an empty group. I'll keep an eye out to see if the error's gone
