      I have a world that has been in use for several years, at least since 2012. I have experienced a few glitches with the world during that time and had to use some tools to reset the world except where my main base is.  However, after one of the updates I started to get a screen that states, "Worlds Using Experimental Settings are not supported...." It creates a back-up and them loads the game. I could choose the option of "I know what I'm doing" and that just loads the game, however I am worried that if something goes wrong, I could lose my world. I have included a screen shot of the error I get.

      According to the Wiki "legacy_biome_init_layer" means that the world type used to be "default_1_1", a long-obsolete world type which was used prior to 1.7 to keep world generation in worlds created in 1.1 the same by omitting jungles from a list of biomes to use:

      legacy_biome_init_layer (Boolean): Whether the world was default_1_1

      Is there going to be a fix to this because I do not want to restart my world.
