2.
3.

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

I expect to see 0/20 dead, but I am seeing 0/18 dead. Same with a 10-man run 0/9 dead, when it should be 0/10 dead.

What version of the product are you using?

XRS 3.1

Do you have an error log of what happened?
No.

Please provide any additional information below.

I posted this as a comment without the screenshots over on Curse:

I just noticed that my XRS isn't quite updating the dead/offline accurately, but it does have the /afk correct!

I have 2 screenshots of my most recent raids where it's accurately 0/20 afk, but 0/18 dead, and 0/18 offline in a OS, and then I have a 10-man Naxx with 0/10 afk, but 0/9 dead and 0/9 offline. When we started the Naxx run, we did only have 9 online, but we added a 10th later. The 20 man always had 20 before we entered any combats.

Screenshots are attached.
