Some notes from core CP:
I agree that events happen too often, but this might just be in comparison with Sukri's events: they tended to happen every 25 turns, and so having your first event appear at turn 8 is a bit odd. I also don't like the look of the event window, but this might just be me comparing it to E&D.
The icon for Events' EUI button is missing - DC_ATLAS_45 or something. More importantly, however, the CP is breaking those icons, as well as the diplomacy icons on the right. I only noticed the missing texture because JFD's EUI patches for RTP and CID fix the NotificationPanel. Lua log didn't seem to say anything in particular, but CP: Events is the prime suspect.
