I've been trying to make a map and I got it to save and it looks all good in the system editor but when I start a game using the system the metal just screws up and isn't where its meant to be. I go back and check the system editor and it still looks fine. I tries so hard to fix but no. It hates me.
Maybe it's the same problem gandalf is talking about here https://forums.uberent.com/threads/pas-files-and-weird-things.67723/ You gotta make sure there is not an extreme amount of decimals behind your heightrange, waterheight, waterdeph or temperature. You can export the map to pas file and remove the decimals from there. That could maybe fix it? I had the same problem. I saw that i had waterheight with like 8 decimals. I removed them and after that it worked fine. I hadn't placed that much stuff on the planet so i just did it ingame, which resets the planet to it's original state, but it worked right after that at least.
