As i just mentioned , the subtypes of some modules have changed , so if it was intentionally or is it a test or a bug … i dunno . E.g. guided repair , guided shield booster energy supply etc. are now engineer category ( a change what should have being mentioned , i think ) and another e.g. some of the formally survival modules have not a category at all .
So dunno if sth. was messed up while the patch , cause if it was a intentional change then they forgot to implement in the shops category. There only warpgate appears as Engineer module. .
I put this into suggestion , cause i guess they forgot it to add in the shop , and there for i suggest to put it in there 
only want some feedback
