                <link>https://bugs.mojang.com/browse/MC-2142</link>
                <project id="10400" key="MC">Minecraft: Java Edition</project>
                    <description>&lt;p&gt;I downloaded a world save file and placed it in my saves folder.. The world save file was in version 1.3.1 . And I click on it to go in the game then the window comes up saying world loading. then it puts me back in the main menu. Then my Environment info i provided above crashed my game... Pretty stupid bug.&lt;br/&gt;
EDIT: May note that i have Optifine Installed. But in the Crash log it does&apos;nt say that its the problem&lt;/p&gt;
