Alright so in trying to get the Wing Commander mod to work i tried downloading and using this mod.. however i had exactly the same instant general failure on startup.. me and the WC mod creator however managed to get both his mod AND this one working with a workarround

(also i did try unsubscribing and deleting the mod then resubscribing again 5 times.. made no difference)

So basically i will just copypaste what i wrote on his forum to help (changing the file name to fit this mod)

****EDIT**** MAJOR correction ****

So after some trial and error i found out when the problem occurs.. it appears that when steam/homeworld copies the .big file from the workshop folder into the dataworshopmods folder that for some reason the .big file is corrupted.. so its a VERY simple fix instead of what i wrote earlier..

Go to

steamapps/workshop/content/******/759628723 (****** is the workshop given number of hwrm)

find STCR.big and copy it to

steamapps/common/homeworld/homeworldrm/DataWorkshopMods/76561197995830187/759628723

Overwriting the .big inthere.. then you should be good to go :) though following any updates these steps might be required again

Hope this helps :)
