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

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 are now running Minecraft version 1.12.2, so you’ll need to use the latest client version to connect to the server. We’ve also increased the map size by 10%!
Hi guys,
just an update to let you know we’re now running Minecraft 1.12 on Survival! We’re keeping the same map, and you’re all keeping everything you’ve had from 1.11. The event/lobby server are still running 1.11.2 but are accessible with the 1.12 client.
To also celebrate, We’ve enabled an extra boost in mcMMO experience gaining until the end of June!
Have fun!
