I just compacted after updating and had 15% compaction - normally under 1%. The update may have added some extra stuff into our databases when updating.
When I clicked ok from that screen, I got a quick message "May wish to re-import your file...", it disappeared (or I clicked ok), then a spinning wheel to show the software was trying to re-do the index. I waited until 10 minutes had gone by and chose to File > Exit.
Waited a couple of minutes and rebooted the program. It took awhile longer than normal to reboot, but finally did to Plan Workspace. Went to People Workspace and it re-indexed normally.
Back to normal (I hope.)
