A recent update to the Steam version of NieR: Automata added support for Korean, Simplified Chinese and Traditional Chinese, but introduced a bug that raised the free space requirement from approximately 50 GB to 366 GB.
What happened
The patch, released around November 5, was the first for the Steam version in five years. Instead of simply adding language files, the installer began treating each DLC of the YoRHa Edition as if it were the size of the base game. As a result, Steam demands enough space for all of them at once, even though the final installed size remains around 40-50 GB.
Square Enix confirmed the issue in an official post, apologized, and stated that the team is investigating the cause and working on a fix. In the meantime, the recommended workaround is to uncheck all DLCs in the game's properties on Steam (Properties → DLC) to download only the base game.
In practice
Players who already have the game installed may not be affected in the same way, but new installs or reinstalls hit the 366 GB barrier. The game itself continues to work normally after a correct download; the problem lies in Steam's space calculation.
