Transcendence

For some reason, about in the middle of my quest, thease words started appearing.
Overlay OnUpdate: Unknown overlay type ### (objAddOverlay obj overlay pos 0) ### [Stalwart-class gunship]: Unknown overlay type ### (objAddOverlay obj overlay pos 0) ###

I was using Aeonic's awesome Stalwart gunship. Could anyone please help me?
EDIT: Here's a full list of mods:
Aeonic's Praetorian, Molotok, Starlight and Stalwart ships.
Bobby's UG Wingmen
soggydoggy's Commenwealth Battle Station
Prophet's Merchent Emporium and Total VUI
Kittehbob's Patch Spider icon replacer
Darth Saber's Commenwealth Debt Card
alterecco's Hash Functions
I believe that's all of them.

it seems to me that you are using also the VUI mod by Prophet and alterecco.
that line of code: (objAddOverlay obj overlay pos 0) is found in DamageIndicator.xml

If you don't give us the full list of mods you are using and a pastie of your debug.log, helping you is going to be nearly impossible.

Yes, that seems to be the VUI causing that.
If it can't find the damage type of the weapon it returns Nil and I need to add a check whether it should proceed from there.
Thanks Corporal Jomn.
