Got a new bug to figure out how to fix. I made a cluster grenade that makes 4 projectiles then 4 more per the previous 4 for a total of 12. This is a flame version of it, seems that some actors become immune to explosive damage.
I'm using 2 different activators to fire 2 different dummy weapons via 2 different scripts, the scripts are just do once and fire weapon. It also seems that you do not gain exp with it do to it not being directly from the player. Is there some sort of script I can toss on the dummy weapons top link them to the player?
I also tested firing 10 custom grenades directly from the weapon and I still run across the random explosive immune creature. I've tested on deathclaws, rad scorpions and cazards or whatever those orange wing things are. Out of the 20 or something human targets I've run across none has gained the immunity. I have even disabled PN, Nevada skies and the fixes nothing seems to cause it.
edit
so far doing alot of testing I found reduce damage resistance set to 1 in a enchantment set to the explosion will allow damage to be done normally, still can not figure out how to get experience from dummy weapons tho...
