Mythic Feats Extra Mythic Power and Extra Path Ability: Can Take Only Once?

[Ninjaxenomorph]

I am planning a Mythic build, and I was trying to figure out how I can squeeze in another Path Ability. It appears the mythic feat Extra Path Ability can only be taken once, as it lacks the 'this ability can be taken up to X times' special text. However, I noticed that right above it, the Extra Mythic Power feat, very similar to other stackable feats such as Extra Hex, Extra Rage, Extra Ki, and Extra Arcane Pool also lacks this.

Extra Mythic Power (Mythic)

You can store more mythic power than your tier would normally allow.
Benefit: You gain two extra uses of mythic power each day.

Extra Path Ability (Mythic)

You can call upon mythic powers beyond those already invested in you.
Prerequisite: 3rd mythic tier.
Benefit: Choose one mythic ability from your path or from the universal path abilities that you meet the prerequisites for. You gain that path ability.

Was this intentional, or was this an oversight?

No, you get their first-tier ability, not one of their path abilities.

Did... did they delete their post?

I don't have anything to add for this specific instance, but there are plenty of "Extra" feats that can only be taken once. Extra Channeling for instance.

Yeah, realized ten seconds after I'd posted I got confused, tried to yank before anyone saw it and got confused too.

I feel it's an oversight personally, but Raw, looks like you can't.
