If I may post another example of this happening. Coincidentally, the same batter who I referenced in my second post in this thread, who was incorrectly awarded two RBI after reaching on a two-out error, just did it again!
I had runners on second and third with two out, this same batter hits a ground ball to the SS, the ball is booted, everyone is safe, and one run scores. The batter is awarded yet another erroneous RBI via the two-out error. It's actually becoming kind of funny, but I'll take the runs!
Hope this helps.
