I do not have a tech for Alloy Hardening listed in my Xenopedia ( I it called Alien Armor Plating in game?), however I have already disassembled cruisers. I am able to build hovertanks, shields, and wolf armor which have Hardening as one of their requirements. So I am assuming I have it.
I do have a reactor tech as well. I can build up to Saracens and Valkyries. I think I pretty much have every tech in the game except the ones you get from raiding a base and singularity. I just loaded it up and tried disassembling a corvette, landing ship, and cruiser and still got nothing. Any other ideas? I am using yesterdays update with the hotfix that fixed landing ships.
I have a battleship core and can't disassemble that either, but I am assuming I need the carrier first.
On an unrelated feedback note, I really like the mod except for the commonness of vortex guns. The problem is two fold. The aliens have no sense of self preservation they just fire of repeated shots wounding and possibly killing themselves in the process. It makes taking alien ships a little silly as they just walk up to me and blast me and themselves in the face. The other problem is they annihilate cover so easily (while doing remakably little damage by comparison). So basically what happens is first shot they destroy the cover nearby and then my guys and the alien just stand out in the middle shooting at each other.
In regular mode, when you take an alien base there is a fun shootout as everyone with everyone hiding behind cover and this is noticeably missing from ID. The shotgun plasma they use is actually more dangerous as well since they become crack shots later on. It kind of makes taking the command center of the alien base boring as I just walk in pump 3 rockets and a few electro grenades in and call it a day.
