I'm a mod of Seterra https://www.speedrun.com/seterra I wanted to add some level, as there are 340 levels and it wouldn't be as useful as just adding them when someone makes a request. So I was moving up the new level and then noticed that a few levels switched. Naturally, I wanted to switch them back, but it behaved as if some levels were ignored while switching. More precisely I had a configuration ... Poland: Voivodeships, Poland: Cities, Russia: Neighboring Countries, Oceania: Countries and Territories ... I wanted to solve them alphabetically, but when I clicked on Oceania "move up", it just switched with Poland: Voivodeships. After some testing I noticed that there was a chunk "Poland: Cities - Russia: Neighboring Countries", they can't be divided by any way and moving up or down totally ignores them. I tried refreshing the page, turning off and on the computer, on phone, and asked the other Mod. All of which failed. :(
Edit: After some more testing when I tried to move up Russia, it behaved in an even more mysterious way I couldn't understand
