I killed the llamas instead so that I could fence him in and have him available at any time. Unfortunately, he somehow snuck out when I was sleeping. Funny that I had two wandering traders appear nearly immediately in my last two worlds but now I see nothing other than I'm nestled in close to two villages, north and south of my spawn point.
So what causes the wandering trader to spawn? I just started up a game that I haven't played since the 16th and had already killed off 5 traders or their llamas (as I have 10 leads in my inventory) and now load into the game and I've got another one at my door, killed him off and now have 12 leads and 2 llamas waiting to be trained.
Yet my newest game has not seen any wandering trades thus far after about 5 hours playing
