Same bonus feat, two different classes

[Jack-of-Blades]

So I'm just curious if you gain the same feat as a bonus feat through two different classes, does it just become a redundant feat, or could I choose a different combat bonus feat?

For example, the first level of Spire Defender Magus, you get Combat Expertise and Dodge. Lore Warden Fighter, at second level, gives you Combat Expertise as a bonus feat even if you wouldn't normally qualify for it.

If I take both of them, do I just end up with a wasted feat or when I gain Combat Expertise a second time, do I get to choose another Combat Feat that I qualify for?

EDIT: I realize in a home game, the GM could rule however they feel, but this is more specifically aimed at PFS.

Wasted feat. Unless it specifies, you don't get to choose anything else.

As per Weables.
SOME GM's will let you swap it out but for the most part you are screwed on it.

[Feral]

It's wasted.

I figured as much, just figured it was a question worth asking.

There was a couple places in old 3.5 where if this came up you'd get some sort of door prize.

I remember the Marshall got Skill Focus: Dipomacy but if you already had it you got another feat instead.
