Broken world gen

It has been like this for a while. Random holes, biomes trying to coexist, missing tiles especially near roads, misshaped and weird land, roads overlapping and more. When i want to start a new playthrough i reveal the map after the first save. If its a nice world gen i rollback and enjoy the game if its not i generate another. I takes about 40 to 60 tries to get a decent world. In one of the photos i sent rocky lands biome, mosaic biome and antlion desert are trying to coexist. This has been like this since the sea changed, very long time. Lands are uneven and have a lot of weird gaps. Some biomes are very tall and thin, some are needlessly big. I am sure it wasn't like this before. I guess this is a very hard thing to fix and would take a lots of time, but if you could it would be great. Have a nice day
