Having what feels like a 1/15 chance of mods actually loading the content so you don't get the infinite running man form hell is an absolute pet peeve of mine. Not a universal issue, not a number one priority, but if a dev sees this please consider trying to fix it. The modding content is so good for this game but it's just a choir for me to play with it. The only 'consistent' method to trying to get mods to work is restart the game at least 5 times waiting 30 secs to a min on the start up screen for the flags of the custom factions to show up so I know it's downloaded properly. If that doesn't work, uninstalling the mods and reinstalling them just to break on the next start up. Favourite mods being middle east escalation and galactic contention and on Australian internet the downloads take from 30-40 mins before I can play the game each start up.
