The mod system should now be functioning correctly.
In early December the developers of Hogwarts Legacy released a minor update. The game officially supports mods, and players had reported issues with how mod information was displayed.
The developers responded:
- They fixed an issue that prevented more than 20 favorited or installed mods from appearing in the system, even when additional mods were present.
This December patch for Hogwarts Legacy does not add new content or change gameplay mechanics.
The previous update, released in October of this year, focused on bug fixes and performance improvements.
