Good thing getting the config files imported solved it. Seemed likely to be the case.
The initiative array is an array containing all the units on the map. It is always sorted so that the item at index 0 is the current pawn, index 1 is the next pawn and the pawn at index array.length -1 will be the previous current pawn. If you for instance want to find the health of the next pawn in initiative you would get a reference to Grid_Manager (or ATBTT_GameMode in the coming update), get the initiative array, get index 1, cast the output node from the getter to Unit_Parent and from the output of the cast get the value of Current Health.
This should work, but if it doesn’t, could you send me a screenshot of how you do the casting?
