* Release 0.1.1 of the Spawnable Event Items mod, including the new December 2020 event items.
I recommend you use AstroModLoader, which you can find binaries for at Github.com, to manage this mod with a user-friendly GUI as well as to seamlessly ensure mod compatibility with most other mods you may wish to install.
You will need a copy of AstroModIntegrator; you can find a binary of it on the Astroneer Modding Discord community or build it from source at Github.com.
On Steam: Place the .pak file in the %localappdata%\Astro\Saved\Paks directory (create it if it does not already exist). Then, run AstroModIntegrator.
On the Windows Store: Place the .pak file in the %localappdata%\Packages\SystemEraSoftworks.29415440E1269_ftk5pbg2rayv2\LocalState\Astro\Saved\Paks directory (create it if it does not already exist). Then, run AstroModIntegrator.
