Things I’ve learned that may help: Only have ONE thing at a time for folks to do. For example, don’t have 2 or 3 mining spots lined up or 2 or more building things going on at the same time, and make sure EVERYthing is in a proper storage location - weapons, for example, won’t be picked up unless they’re in a proper storage spot. Also, check your crafters inventory for an item he doesn’t have supplies for - this may be putting the brakes on his other items.
There’s still a lot of things broken, but then that’s what Alpha’s about I suppose. It’s not supposed to be a complete playable game yet (though we’re chomping at the bit for it). Doesn’t make it any less frustrating though…
