the older version limited the take out to max 6 item (one for each underverse add-on). The new version is purely interactive: You apply a mysterious cube on the cargo terminal and you can take out up 6 items too. repeatable, cube is consumed.
One item can be taken out per under verse add-on which you have in this subsystem. Not cloaking add-on not any other add-on but under verse add-on. That should definitely work because it has not been changed for awhile.
Huh, I definitely checked the walkthrough and I couldn't find anything. And with the bots, I'm almost sure I had those things in the cargo when I tried to trade. I'll check next time I get a chance to make sure.
