I’ll try to answer your last question. All enemies and NPC’s are spawned dynamically. So, you need a RM (Replica Manager) which generate new enemies after some time. Sadly, the other devs and me don’t know how to fully use & implement the RM. Your spawnpoint also only can be changed by RM. This means you will have to wait (or help developing).

As long as you hope, you can.
