I'll preface this by stating that I'm playing with some mods that likely caused the specific issue that made me make this thread, but I think the underlying issue is not mood related.
Basically, I found a legion XIV with built in DTC, which really sucks because ITU is a straight upgrade that I can never use on the ship now. I think it should either be impossible to get DTC built in on a ship, or it should be possible to upgrade it to ITU. I honestly think DTC should just never be built in on AI ships in general, it doesn't make sense to do it when ITU exists.
