I just had 3 owners vote against an OL trade of mine that saw me acquiring a 1 effectiveness AAA pitcher for a crappy AAA hitter. Point being, OL owners LOVE voting against fair trades, never mind clearly lopsided ones. So how did this trade even go through?
Also, are you going to send a ticket to Admin? As you well know, there are a lot of aliases playing on this site. I'd ask Admin to look into whether the two teams are run by the same person.
