Hi! i'm new to this and I need help. Recently I tried to "downgrade" my 1.15.1 spigot server to 1.14.4 version. Everything went well except the map, when I entered the server the map was completely "new" and all the buildings and changes were removed and this appeared on console: 23.01 19:22:52 [Server] INFO java.lang.ArrayIndexOutOfBoundsException: null 23.01 19:22:52 [Server] Server thread/ERROR Couldn't load chunk [98, -186] 23.01 19:22:52 [Server] INFO java.lang.ArrayIndexOutOfBoundsException: null 23.01 19:22:52 [Server] Server thread/ERROR Couldn't load chunk [99, -186] 23.01 19:22:52 [Server] INFO java.lang.ArrayIndexOutOfBoundsException: null 23.01 19:22:52 [Server] Server thread/ERROR Couldn't load chunk [100, -186] 23.01 19:22:52 [Server] INFO java.lang.ArrayIndexOutOfBoundsException: null 23.01 19:22:52 [Server] Server thread/ERROR Couldn't load chunk [101, -186] 23.01 19:22:52 [Server] INFO java.lang.ArrayIndexOutOfBoundsException: null 23.01 19:22:52 [Server] Server thread/ERROR Couldn't load chunk [102, -186] 23.01 19:22:52 [Server] INFO java.lang.ArrayIndexOutOfBoundsException: null 23.01 19:22:52 [Server] Server thread/ERROR Couldn't load chunk [103, -186] 23.01 19:22:52 [Server] INFO java.lang.ArrayIndexOutOfBoundsException: null 23.01 19:22:52 [Server] Server thread/ERROR Couldn't load chunk [104, -186] 23.01 19:22:52 [Server] INFO java.lang.ArrayIndexOutOfBoundsException: null 23.01 19:22:52 [Server] Server thread/ERROR Couldn't load chunk [105, -186] 23.01 19:22:52 [Server] INFO java.lang.ArrayIndexOutOfBoundsException: null 23.01 19:22:52 [Server] Server thread/ERROR Couldn't load chunk [105, -185] 23.01 19:22:52 [Server] INFO java.lang.ArrayIndexOutOfBoundsException: null such a message but much longer... What can I do to be able to play in 1.14.4 without losing the progress of the map? (I have map backup) thanks and sorry about my english :c
Since the dawn of MC I don't think you have ever been able to downgrade a "map" (world). Im pretty sure the client even has a giant warning regarding this when you open an old world in a newer game version (ie: open a 1.14.4 world on a 1.15.2 client = big warning) If you have a backup of your world from 1.14.x, use that world. If you do not have a backup, you're SOL. On top of all that, 1.14.x has been one of the worst MC updates in a very very long time. Why in the world would you want to downgrade from 1.15.x -> 1.14.x?
I SHALL FIND OUT! I have waaay to many MC versions that i do literally nothing with Edit: Only seeing migration of old data, nothing about downgrading
