In my reputation summary I have this entry:
+40 / -32 23:29 8 events Java Getter Methods - Best Practices
But when I look at the answer itself, it shows only two events, a single up and downvote (which I believe to be the correct set of events).
I also noticed that my rep was probably adjusted by -8 recently, which could be linked to this. Although in that case the adjustment overshot the correct magnitude by 2.
