Same type weapon damage bonuses not stacking

[God_In_Action]

Description
==========
I have a Dwarven Rune Axe weapon with a +1d4 divine bonus damage enchanted onto it from a basin. When I apply a +1d6 divine temporary essence, only the 1d6 bonus is applied. I have tested this against enemies without divine immunity or resistance that I know of (including Crinti, Underdark Spiders and the Minotaur and Azer in the UD slave pit cage fight). When I apply a temporary essence of a different damage type, both types are applied.

Steps to reproduce
----------------------------
Take a weapon with a dweomercraft damage bonus, apply a temporary essence of identical damage type.

Expected result
-----------------------
I should be seeing non-critical rolls of 2-10, and there shouldn't be any 1s.

Actual result
-------------------
I have looked at the combat log and I only ever do 1-6 divine damage without a critical hit.

Note the 1 divine damage below.



Here is the same weapon now with an electric temporary essence applied.

Same damage types don't stack as per how vanilla NWN engine works. I recommend putting on 1d6 positive temp essence instead of divine so they start stacking.

That's a shame, I quite like Divine since fewer things seem resistant to it.
