The frogs have arrived at MCAU.
The map will be expanded to accommodate our new little friends.

Hey Miners and/or Crafters,
As of 11/07/2021, the MCAU server has been upgraded to version 1.17 with the addition of the new caves from the upcoming 1.18 update! Accompanying the update, a new map was released with resets to player mcmmo skills and the in-game economy.
Since the release of the new map, the server has seen many new and old faces return to the server. So why not jump on and join us!
Please note that another world reset is planned for late 2021 upon the release of Minecraft 1.18.
Hi guys, quick write-up for some small things that have been going on.
If you want the technical solution (and backstory) to how I fixed the old maps, keep reading…
As we moved from 1.12 to 1.13 how blocks get stored in region files changed. Blocks are no longer stored as numerical IDs, but rather now as words. For example, “1” is now “minecraft:stone”. Now, the conversion for this was supposed to be pretty straight-forward, chunks get converted as a player steps into the chunk for the first time prior to conversion. Except, this was causing the server to crash.
So, after months of this happening I was getting pretty frustrated. I tried converting the maps in single player to the new world formats, or using “MinecraftRegionFixer”, but all they did was cause the chunks to completely regenerate to nothing. Up to 25% of the maps were getting regenerated.
Then I found out that Minecraft servers have a –forceUpdate flag (From this link) that can be used to convert worlds, so I tried that using Vanilla. Same problem. Then I found something else that said maps that were generated when running SpigotMC (An extension of Bukkit) had to be updated using SpigotMC. But, this is what we were doing originally, and it was crashing the server…
If your server is/was a Spigot server you will need to use CraftBukkit/Spigot to convert the world. Spigot in 1.12 didn’t set the “LightPopulated” flag, so that vanilla Minecraft will reset those chunks.
The solution was to use SpigotMCÂ and the –forceUpdate flag on all of the old maps since 1.5 (When we started using SpigotMC), and 72 hours later, all the maps are good to go.
Rant over.
Enjoy 🙂
We’re getting closer to being able to release the new 1.13 map. There’s still some crucial things that haven’t received an update yet, so currently there is no planned date for release other than “soon™”. A new map means that the current map will go into read-only and your inventory will not be transferred over.
Full details on the update will come later when we have an official date.
Confirmed changes for 1.13 so far:
