Ok, somebody wanted me to make a schematic for them, which I did. But when I try and trade the schematic to them, the trade cancels immediately after I put the schematic in the trade box. The other guy has plenty of room in his datapad.

Bug? Feature? Supposed to be transfering them some other way that I'm supposed to know about by telepathy straight to the game developers?

And is it just me, or do other people find the trade mechanism totally **edit**, with its constant cancellations?
