 Description   

If you have maps that were created way back when (the original chunk format), minecraft will no longer offer to convert them.

(I don't know if this was removed purposefully, I had to use MCNostalgia to downgrade to a beta pre-anvil version, then load the map, and upgrade with the older version)

Step 1: Using the new launcher, load version "release 1.1"
Step 2: Convert the world with that version.
Step 3: Load latest version.
Step 4: Convert the world with the latest version.

MC-5672 was about worlds created from third-party software, and marked invalid because of that.
MC-22449 was about worlds created in Minecraft.

You're right, MC-22449 is dupe of MC-5672.

Comment by Alex Campbell [ 16/Jul/13 ]

Is MC-22449 really a duplicate of this?
This is about having no option to convert alpha/chunk-format worlds.
MC-22449 is about crashing when converting beta/region-format worlds.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Your attached world is not shown in my world list.
This world must be very old, it's a pre-Beta 1.3 format, not even pre-Anvil, it's pre-Region.

To my knowledge, I should be able to just throw this in .minecraft/saves, and it should show up in the world list stating "Must be converted".

An effected map (Generated using Beta 1.2_02)

Comment by Kumasasa [ 28/Dec/12 ]

Can you please attach here an old world (prior conversion)
