I just researched the disruptor beam and I expected to install it as spinal mount on my titans, but the weapon does not have the mod. That is unexpected, since the tip says it is a beam weapon. BTW Chaos Chain, which is also a beam weapon, does not have this mod either. And an unrelated cosmetic bug: the Imperial Archive tech description contains the same string duplicated "Turns to rival steal tech missions set up time". The game version is 1.3.4 and here is link to my save where you can see Disruptor Beam missing the mod: https://drive.google.com/file/d/1dQhnXWNobA85KaBzuDiKmsa7F2IJR-Ko/view?usp=sharing Spoiler: screenshots
Please disregard my report - I've just noticed that tooltip for the tech lists available modifications, and Disruptor Beam is documented not to have that mod. But my report about duplicate string in Imperial Archive still stands
