Dimension Fix Mod fixes dimensions all being removed when 1 gets removed. This mod is port of Minecraft Forge issue #7527 (Make UnboundedMapCodec more lenient in decoding dimensions) and #7599 (Fix worlds that are missing vanilla dimensions in the level.dat). It also fixes MC-197860 (Deleting a custom dimension in a datapack deletes Nether and End).
