Yes, this is a temporary map. Still, it's fun to play and build a small community with each other. It's why I share my food and my mine with people. Plus, it's a really good practice of managing the new food bar and getting yourself enough food to stay alive when setting up.
Plus, we don't know if this world is going to be up for 2 days or for 2 weeks, so use it, enjoy it, and be neighborly. I'll gladly help anyone who needs it when I'm on.
Besides, I believe the plans for how we'll handle the permanent world + adventure world is still being discussed and finalized, so hang in there, and we'll get this stuff around to you as soon as possible!
