It would seem that I ran into a trading bug today...I opened my trading on the Market, and when trying to sell a Prime Warframe set, not all of the pieces that I had were showing as available for the trade...and example I would be trying to trade Rhino Prime, and in the trade UI, it would only allow show me, say, the BP and the Chassis, and any related Relics...Now, I verified in both the Foundry and in my Inventory that I had all the required parts to sell (BP, Neuros, Systems, Chassis) all built and ready to trade...this has happened to me today with 2 different frames, Rhino Prime and Revenant Prime...As I said, I verified I had all the parts to trade the full sets...I tried quitting out of the game and restarting, and this issue persisted...
I was able to trade weapon sets and riven mods without issue...any help would be greatly appreciated...thanks!
