Whenever I download the G.E.M on steam it doesn't download properly. It 'downloads' in an instant and when I open the Rome 2 launcher it doesn't let me play as it says mod is still updating and when I look in the list of mods it appears as if G.E.M is still downloading, yet no progress is being made. This has happened to other mods I have tried to download in the past like DEI. Does anyone know what to do? Thanks
