I would produce more xml info but this is all that seems relevant to the convo so far. If this has been fixed in your build I understand. At the very least this leads itself to typo or lack of updating descriptions on tech changes which has happened a bit when techs are redesigned like the Thalan Hyperion Matrix. This is all data files so I don't fault for that aside from your answer(no offense intended{rereading this it sounds possibly like that, i'm just trying to provide as much info as i can]).
P.S. i am not sure if this exists in the other tech tree files, just checked the terran since well it's the most common.
