What happened?

With the latest releases of BetterEnd and BCLib, there are no chunk errors, but no BYG end biomes can be located with /locate biome when using the BetterX world type. With the Default world type, biomes from both mods are present, but there are some other issues. The first time I tried to fly around in the end, my game crashed (log below); when I loaded back into the world, the game did not crash, but I noticed a weird biome border (image below). Also reported in AOCAWOL/BYG#836

I did resolve the first issue (betterx-preset not including big biomes) Do you have the seed and location for the screenshot you posted above?

Should be fixed with the just released BCLib 2.0.11.
