It happens. A lot. It has since 2009, so you have to get used to it.
The one thing I always wanted was a Vmax wiki. Just a straight up wiki (like Wikipedia) with the information only on the Vmax and it's parts in the appropriate section and year model where anybody could move things to where they should be and enter new information as it came available.
I actually started one once years ago, but got tired of being the only one doing all the entry and gave up.
