Neither my wife nor I can use the trade terminals since the patch. We had only been on next island 48 hours before patch, but there was no problem until after. We have both logged, and tried different locations. Right now we are both in Club Neverdie and I can confirm neither of us can use the trade, but all other functions including Auction, technician, crafting and storage all work fine. As do all other npc's we have come across.
May I suggest everyone sends a support case on this issue, so that MA fixes this very serious bug asap. Trade terminals don't work on Next Island and, in this situation, the game is simply "broken".
