Hi, It is my first time since ever playing this game that I have had to post a bug report. Normally I can resolve the issues myself but this time I am really quite stumped has to what is causing the issue. I created a custom scenario for the new Alpha 10.5 using the Solar System Generator and some custom template files (planetary playfields) and started a dedicated host for it. The system has been running fine for almost 3 weeks when this week I had reports of ships vanishing in orbit of the starter planet. I didn't think much of it at the time has I've had similar reports in the past and it were usually a case of misplacement. After some investigation it appear that the reports were accurate, so from what I have been able to determine, all orbits playfields appear to be suffering the same issue. Ships flown or spawned in orbit playfields are fine if they are occupied, but the moment they aren't they flicker then vanish from view leaving only their marker. A run of ents -all -full appears to confirm their marker location but when setposition is ran or destroy on the ID's I get a message saying the entity id doesn't exist. It is if the game has only recorded the reference to the entity but now the entity itself. I have been able to reproduce this issue in multiple orbits, but it doesn't appear to happen in any planetary playfields. Now I grabbed the dedi save game and loaded it up locally on my PC for further debugging and the issue occurs there as well. I delete the saved world data for the affected orbit to force a rebuild from the template and repeated the process of spawning a ship in orbit only to watch it appear then immediately vanish. I have restarted the game again with the same scenario file and had the same issues occur again. The only time I haven't had the same issue is if I start a new game using my templated playfields with the default game scenario, then everything works fine. All of this appears to indicate that something about my custom scenario isn't working correctly, however, I have changed any orbit templates when using the solar system generator, only planetary playfields template. I am hoping someone else has encountered this issue and has a fix for it, I'd rather not like to have to restart a new dedi server again if I can help it. Thank you in advance for any advice or assistance you can provide.
