Attacking Timer Issue

When an opponent is in the hospital, and I'm watching their countdown timer.. Once it hits 0 seconds, and then the gun icon lights up to attack them again, I tap it.

The screen then switches over to the attack screen, but another timer begins to start counting down for an additional minute. Sometimes it says Join (if they're beinf attacked by someone else) or Start (if not), but the button to press to initiate the attack is blacked out, and a new timer is counting down from 1 minute.

This doesn't seem to be happening to others though, as I've lost out on several hitlist targets, and am unable to hit targets during wars. Have I missed something that's causing this, or is this a bug? 

Because the person you're trying to hit is in a ranked war, but not against you, so there's a 1 minute cooldown to prevent mercs.

(I think that's right)

Two issues with that.. 

It hasnt happened before, until just this past week. Sniping attacks as a merc away from RW opponents has always been a thing, without an additional timer being involved. 

And.. it isnt just RW participants (that I noticed anyway).

If that IS the case.. this is a new thing? I looked back at Chedburn's update announcements prior to posting this report, but didn't see anything. IS it a new thing that's been added/incorporated into Torn?

It’s been a thing for over a year now. Announcement

there is also a 15 second countdown when someone lands after flying - both abroad and when they land back in Torn, in case you are not aware of that.
