I don't know if this is a glitch or a change from original SS 2.0 :
[spoilers]
After turning on transmission on deck 5 I didn't get the order to get to deck 6... but to go back to 4 and reprogram sim units again. Well, I've gone down there but I can't even interact with sim units without another card (or set of 3 cards probably). Is this some glitch or is this normal and I should just solve it?

Well I have done that before with all 3 of them and cards got consumed.
It seems it gave me the yellow card again directly to inventory, so after some running around I'm done with this part. Thanks for reply anyway.
