As you can see, neither Vona or Muldrotha were played during the turn so neither had summoning sickness. Neither of them was disabled obviously since they both attacked. Settle only exiled Vona and was destroyed, then Muldrotha was able to strike the opponent.

Agreed, I see the same behavior.
When creature exile by other card effect (my case is Terefi 3rd ability) Settle the Wreckage is destroy too.
I have the same problem. Only exiled the 1st attacking creature then it pops and goes away then the rest of the creatures finish attacking
Also seeing the same. Came here to report that exactly
Oh
Also, if the AI triggers my Settle the Wreckage, not only will mine go away, but so does theirs if they have one on the field.
For me too. 
same.
BUT ALSO:
Using Teferi with his Zhalfir token out (not major), Nyx on the board, as well as Settle the wreckage.
Two creatures attack, 1 gets exiled while the other does damage. Settle the wreckage gets destroyed. My turn, Nyx brings back settle, opponents remaining creature gets exiled and my Settle the wreckage gets destroyed (at the start of my turn).
If the Zhalfir token gets destroyed, Nyx brings back Settle the wreckage and it stays on the board without getting destroyed.
I can confirm, I have faced it a few times. New bug saved my bacon (but sadly still needs to be fixed)
The support itself is destroyed after the first creature exiles instead of at the end of the turn. It is taking the extra errata that StW puts on a creature away from the remaining attackers
I suspect this was meant to fix the issue with StW not getting destroyed it the opponent’s last creature doesn’t attack (summoning sickness usually). However, until they actually make StW get destroyed at end of turn, it’s not going to work properly.
Thanks for all the info everyone. There definitely, seems to be some odd behavior going on here. I’ll pass this up for investigation, and add this to the bug list.
I had one settle in battlefield.
Opponents turn and IA threw it’s own settle.
Opponent attacked me with it’s Darigaaz, and Darigazz and my settle disappeared and IA’s settle disappeared also.
I know it’s not just this easy, but you might give it “at end of turn, destroy this” to the wreckage instead of the creatures it exiles. The big problem that I see with this is it not working with starfield/Karn ult, but at least it would work properly.
Came here to report this. Thanks @Brigby for staying on top of this.
Hi Everyone. This should be fixed in 2.9
Fixed in 2.9, tested in story mode, but it has been nerfed or it has another bug.
Now when the creatures of the opponent attack you receive the damage and after the creature is exiled. This is not the way it used to works, used to exile creatures before making damage.
Can you tell us if this is intended? @Brigby
If you still take the damage the card is pretty much useless. I would assume this is a new bug
(also I think @Tombstone handles bugs more than Brigby)
Confirmed, the creatures are now exiled after combat damage is dealt. The combat log also reads as the creature being exiled by it’s controller, not the support.
But at least it’s all of them again?
