Seeing Rekt is in the forest, we will need a mod once we start playing again. Even though we don´t use traders not nearly as much as the YT meta abusing min/max addicts, i still don´t wanna have to deal with him early game. In fact we usually avoid him as much as possible.
I wish there would be a no trader setting when creating the world. But i guess the whole new challenge system doesn´t allow that. While i think you can simply ignore the challenges, the game might be acting up if a challenge involves a trader and there is none.
