Hey everyone,
The team has discussed about this issue with the “mixed” listings and the conclusion is that they are allowed, if the items that are being sold in the bundle do the same action in-game and in the same game.
Example: Mixed Traps - Fortnite STW
All the traps are made to cause damage to NPC zombies inside Save The World. The only aspect that changes is the visuals on each trap, but all of them have the same functionality, which is to defend a certain area of the game and cause damage to NPCs.
In case a user wants certain traps, then they would need to request on the listings comments to verify if the seller is able to provide that certain trap.
Hope everyone has an awesome day!
God Speed!
