Ok, it's not a problem, but, as the title says, it's weird! Kristina was repairing the floor, then action changed to nothing. Then it went back to repairing floor! I didn't touch her! It just happened! Weird

I believe that happens when your peep has finished a "cycle" (work, repair, etc) and the game "decides" what your peep should do next. In this case, the peep finished a repair cycle, then stopped to think about what to do next; then the game had your peep continue to repair the floor.

This has happened to me, but only on house upgrades, and only with the older couples. Sometimes it looks like they are floating towards the room that was upgraded, but their action is blank. It hasn't done that on the younger family members yet. And yes I am running the latest upgrade.
