SSA 4x merit rewards

[Zhym]

Have the rules for getting 4x merit rewards in an SSA changed lately?

 

I started running though Who Will Die? this afternoon for the first time on a toon.  When I finished the second episode, the option to get 4x merit rewards wasn't available because "[y]ou can only receive this reward from repeating Signature Story Arcs once every 7 days."  But I hadn't repeated the arc, or the episode.  I did WWD3 just to see if that was a glitch with WWD2, but it did the same thing. 

 

I know I've done WWD all the way through in a single day before and gotten 4x merits each time, so is this a recent change?  Or is something bugged?

 

FWIW, this toon (current a hero) had done WWD as a rogue, but well over a week ago.  I don't know if that could have affected things.

I think this might explain it:

So normal behavior is that running any SSA resets the 7-day timer for all SSAs, but the first time for each SSA counts as a freebie.  What seems to be happening here is that you only get one "first time," regardless of alignment, even though the arcs are actually different between heroes and villains.
