Question about Winding Waters South spawn DR

[Fury_US]

Since the institution of spawns on the Winding Water South map, my group has been mercilessly killing them (huzzah for the actual frontline action, btw- thank you!). One thing I have noticed, however, is that the devil spawns (there are imps, lemures, and spinagons) do not seem to have the weakness to silver that devils should by lore. I have used a pair of silver daggers and a pair of acid daggers (needed for the troll spawns), and the DR has been recorded the same for both sets of weapons.

The spawns themselves are not overly difficult to handle (though the spinagons definitely pack a punch for squishy types like Wren), and so it's not something that I feel makes things unnecessarily hard- in fact, I'd say the spawns could use a bit more of a challenge rating. I'm just bringing this up to see if it was intentional that silver weapons not bypass the DR, or if that was an oversight?

I've tested this as well, with a cold iron weapon (with the guess that DR types may have been mixed up) and a silver one and no DR was bypassed.

These spawns are CR 15-16 (and below).

Other areas meant to represent the frontline are yet to come, with higher CRs. For the vulnerability to alchemical silver I'll look that up.

I am extraordinarily happy about future maps with increasing threat. We've been having a blast RPing out there, so thanks all around!
