I've had this issue, but not on the receiving end. When I tried to trade with player "Hont" both today and yesterday on (EU) Survival he never got a trade popup, though I would receive them just fine from him.

Attempted to replicate. Put exactly 1921 scrap into machine and had 38 springs on me. Buying springs for 20 scrap each.
No issue

Also attempted reverse: 38 springs in machine selling for 20 scrap each.
No issue

Technically I have 'reproduced' the issue by filling all vending machine slots with scrap. Selling springs to the machine the springs fall out the back instead of replacing the empty slots that would be produced by giving the scrap to the player.

@MercedesCLA45AMG Was your vending machine nearly full, or entirely empty when you tried this?

This is the typical issue on Survival as well, but the current situation is different from those normal issues. Trades will not 'sometimes' work with the "No One" glitch, trades always fail. No one on the entire server can trade with anyone else right now.
