            <title>[MC-5446] Conversion from old formats no longer works</title>
                <link>https://bugs.mojang.com/browse/MC-5446</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;If you have maps that were created way back when (the original chunk format), minecraft will no longer offer to convert them. &lt;/p&gt;

&lt;p&gt;(I don&apos;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)&lt;/p&gt;</description>

This is about having no option to convert alpha/chunk-format worlds.&lt;br/&gt;

This world must be very old, it&apos;s a pre-Beta 1.3 format, not even pre-Anvil, it&apos;s pre-Region.&lt;/p&gt;</comment>
