I'm pretty sure Bogolation has too many scruples to sell something he feels is defective.
That said, I doubt there will be a problem with this neck. Once upon a time I worked in a furniture factory, and this looks like a pretty stable piece of wood to me.
In any event, I wouldn't let the bass just sit. Play it, man!
Bongolation, I hope this will work out to your satisfaction one way or the other.
Maybe I didn't make myself clear. What I ment was as it stands now there is nothing wrong with the neck another person may say "No big deal I want the bass" that way Bongolation doesn't have to bother with a neck that might go bad in the future. I could be wrong but I don't think Fender will replace a neck based on appearance.
