I updated my Ubuntu Linux server from StarMade 0.19318 to 0.19361 yesterday. On update, StarMade.jar in the ./StarMade/ folder was corrupted from the StarMade launcher update, so I had to reinstall the game completely in another directory, find the inode of the original StarMade.jar and delete it, then copy the new StarMade.jar to the current game server directory. The server then started successfully.
However, upon logging in, I spawned in space outside of our homeworld. The homeworld is now a large blue ball of light and an NPC shop with a shopkeeper. All ships, docked objects, and most NPC are gone. The planet is not in the center of the blue ball of light - you can fly completely through it. The planet still appears on the starmap, however, it's a blue ball of light. Another planet in the system also appears on the starmap, but is not there when you fly to it. If I can upload files here after this initial report, I will upload a version 0.19318 world0 map, and the corrupted version 0.19361 world0 map so you can load it under those versions to see what happened. I also tried restoring the world0 from backup, and it still does the same under 0.19361.
