Hmm, I’m not seeing what you’re seeing. The initiative bar should not affect initiative order at all. There is no “Use Initiative” variable, only one for using the initiative bar, which is just for displaying the order. You are using the latest version and have not made any other changes to the example map? This is what I’m seeing:

Hmm, again not what I’m seeing on my side. Everything seems to be working fine. You’ve created a fresh ATBTT project and chosen 4.20 after CreateProject?
No worries 
Still need to make plenty more, but hopefully this will be enough for a while.
