Kudos to Tehom, a feature request I put in was implemented within an hour... that's pretty responsive.
The issue in particular was that I had a private +event in (which don't show up on +events for anyone except those invited) but someone else put a big political +event later on (with possible ties to the metaplot) an hour before mine. Although "there's too many things to do!" is a really nice problem to have, it still sucks for players to have to choose which one to attend one day and have none the next.
