I am really missing a trade option to trade with another player.
The only option I can think of is to drop an item on the ground and then the other player needs to pick it up.
But then there is the risk of another qucik player running by and picking up what you just dropped on the ground and also that the graphic bugs out and the dropped item disapear.
If you are in the same clan then you can trade by putting an item in a box or crafting station and make it safe like that.
So a trade option by pressing interact key (default is E for PC users) on another players and choose trade
