Then, you can try to add the items one by one and see which item is not working properly. You could also try to remove the items from the trade first and add them back.
I try. I deleted all games from my trade ( http://dispenser.tf/trade/144139/ ) , except one. Save. After I added the game one by one and tried to save.
Result: I was able to add only 2 Saint Row from 7.
these games (Saint Row x 5) and many other games, which I removed from other trades (for example: Batman Arkham Origins x 2 , Assassin's Creed Freedom Cry x 2) - I can not add to trade. And I can not use them to create a new trade.
UPD. 1 Feb: after transfer to another shop and back to my shop, I was able to use these games to create a new trade.
----------------------
UPD #2 4 Feb: I transfer new games in shop inventory.
I select a few games try to create a new trade.
1. if I edit Wish List and Save - all good.
2. if i edit "SELL ITEMS SELECTION" (add one more game) - I get an error.
So ( http://dispenser.tf/trade/157353/ ),
a.) I choose 5x Battleblock Theater, 1x Insanely Twisted Shadow Planet and 2x Red Faction, "+Trade" button , edit Wish List, Save - all good.
b.) I choose 5x Battleblock Theater, 1x Insanely Twisted Shadow Planet, "+Trade" button, SELL ITEMS SELECTION -> Gifts , choose to add 2x Red Faction, edit Wish List, Save - error.
I can create new Game trades, but I can not edit using "SELL ITEMS SELECTION".
