Hmm, just taking a look through the components.txt file under massive shield depleter i noticed this
From normal SEIV data files...
Tech Area Req 1 := Massive Shield Depleting Weapons
Tech Level Req 1 := 1
From proportions data files...
Tech Area Req 1 := Massive Shield Depleting Weapons
Tech Level Req 1 := 2
If the ruins only gave u massive shield depleting weapons level 1 then u cant build the component because you dont have a high enough tech level in that area to build it
I think thats what the problem is here... i could be wrong though. PVK could say for sure
