That's not specified anywhere that I could find. It clearly should be.
Anyway, it doesn't make a difference to the behavior I'm now experiencing, separate from EUI concerns (either with none, or with it installed manually, same difference)
What happens now, with only the (1. Community Patch) installed and selected, is a spinning wheel freeze while processing AI turns, beginning around turn 10 of the game (first 10 turns of the game work fine). I've reproduced this 5 times with different new games.
Edit: Just tried again, this time with all options installed and enabled (1-6a), which I hadn't tried for long before. Same behavior: Infinite spinning wheel on turn 14 while "Processing Turn for Player 5", in this case.
So it doesn't appear I can use this mod at all, in any configuration
