The Main and AOE icons show no actions after the latest update.

After doing some digging it seems that anything that includes the SoulFragments() function is failing. Replacing it with a basic BuffStacks(#####) seems to work.

Looking around for this problem, found this. Thanks Thunderchylde. The exact change is to change all:
SoulFragments()
to:
BuffStacks(soul_fragments)

that's what I did yes, I don't know if there is other logic in the SoulFragments() function but BuffStacks(soul_fragments) seems to cover what I need it to.

Which file are you making these changes in ?

I was just making the change in a copy of the Vengeance script (copied to a custom script)
