I've not played the game for about six months and came back to it yesterday. I started a game with nearly all my old mods from back then, plus a new Pokiehl mod, Civilizations Expanded, but around the mid-teens turn, my UI disappeared completely and when I hit Escape, a number of the options where greyed out - Load/Save game etc. I've been unable to bring back the UI at all. I was able to log out of the game just fine though. I turned off the new CE mod and tried another game and the same thing happened, again around a mid teens turn. I then looked at all the Steam Workshop for all my existing mods for any chatter relating to disappearing UI and the only mention of it was on Sukritact's Ethiopia mod which I didn't have active, but I unsubscribed anyway. That didn't help. Soon, I will start turning half of my mods to narrow which one might be causing it, but I thought I'd ask the community first if they've come across this recently. If they know of mods that might cause this, or suspect that my game may be corrupted and need a reinstall - it's been sitting on my desktop installed, but unplayed for months.
