Community Mods disappeared for a short while, and with it the Companion Mod functionality that Legion Expansion depended upon to work. These have now been reintroduced to the game and so the Legion Expansion is working once more.
If you have installed PA Mod Manager, be sure to disable all mods within it before using the in-game Community Mods functionality.
Upon starting Planetary Annihilation you should see a yellow box at the bottom of the menu screen. It will ask you if you want to enable community mods functionality, and to do so you must click ENABLE and then restart Planetary Annihilation. Once done you will need to reinstall the Legion Expansion.
Note that all players must have enabled Community Mods in their game, otherwise they will not receive the Legion Expansion client mod, which will lead to missing elements or crashes when the lobby launches.
