The missions are still being worked on, so only the first mission of getting to Bob works. The imagination orbs will not spawn until Egmo’s team finalizes the missions, or at least until they get that game mechanic figured out. Give them time, as they must work with rebuilding a server that they have no idea how it was written originally, and are also working off of little (guesswork) documentation.
I just joined today, and will be installing the client in a couple hours, and looking under the Public server list here, none of them seem to have entity spawning. Is this something that is coming soon, or is it already implemented?
