Yes, the server will keep all data until it is open and when it will be closed. For the moment I don't know about how to make the log, I mean to save it in each folder with player name or save it in same folder. Client won't download the log from server, it will save own log. With sended data and received (text and maybe vessels data). Sincerely I don't remember about the time warp. Right now it is disable now ... So, you can't warp and time will be global on server. "Are vessels that have been interacted with in the future banned from interacting with the world?" - I don't understand it ... Sorry ... Yes we will try to make it different as against KMP. For now we try to makeing the server, we find the bug and we try to fix it. (We will release it in Pre-Alpha, but I'm not sure if Markus want.) Edit: Mefi282 - "witch are both from the same vessel" what you mean? And yes you will be able play with your brother .
