Problem with Homebrew Monster CR Calculation

[rollforyourstory]

Hey Everyone,

I'm making a bunch of homebrew monsters for a campaign that I'm putting together, but I'm having a problem with random encounter CR calculations. The encounter generates but when I click the button to calculate the CR, I get the error "Script Error: [string "button_refreshcr"]:1: attempt to call field 'calcBattleCR' (a nil value)"

Is there a way to get this to work?

It works for me with all my homebrew NPCs. Do you have both CR and XP values in each NPC? Next thing I would check is to see if you have any extensions. If so, try it with them ALL disabled and see if it repeats.

Let us know.

I found the issue. It was an extension to the Vitality variant rule. That extension also gives me some other issues as well but ill post them on that thread.

Thanks for the trouble shooting advice!
