After 20 in game days have passed, no wandering traders have spawned. I have made a device with command blocks that teleports any existing wandering trader to a certain location, activating a tripwire pushing a block. So far, this device has not activated and 0 blocks have been pushed.

How to recreate:

• Create a new world
• Wait some time, wandering traders do not spawn
