I was playing in an Ipad.

Description:
I cast Settle the Wreckage during the combat step after my opponent declared an attack with 8x Phoenix Fleet Airship. Instead of exiling all 8 attacking creatures as expected, the spell resolved by exiling only one Phoenix Fleet Airship. The remaining 7 Phoenix Fleet Airships stayed on the battlefield.

Expected Behavior:
Settle the Wreckage states: "Exile target player's attacking creatures..."

All 8 Phoenix Fleet Airships were legally declared as attacking creatures when Settle the Wreckage was cast and resolved. All 8 attacking creatures should have been exiled simultaneously in a single resolution step.

Actual Behavior:
Only 1 Phoenix Fleet Airship was exiled. The other 7 remained on the battlefield as attacking creatures.

(Hypothesis: The game engine may be processing the exile effect sequentially rather than simultaneously, causing remaining crewed Vehicles/attacking permanents to check status incorrectly during resolution.)

Steps to Reproduce:
Have the opponent attack with multiple (e.g., 8) crewed Phoenix Fleet Airships.

Cast Settle the Wreckage during the combat phase targeting the attacking player.

Observe how many attacking creatures are exiled upon resolution.
