Check for the documented mission-completion fix
If a S.O.N.A.R. mission is not completing even though the required number of enemies has been destroyed, version 1.0.2.0 contains an official fix for that specific problem. The developer describes it as a rare issue affecting some missions. Check that your installed game includes the patch before assuming your crew has missed another enemy.
The changelog was published on October 30, 2026. It establishes that the completion problem existed and that the update addressed it, but it does not identify every affected mission or explain whether an already stuck session can finish immediately after updating.
Match the symptom before choosing a solution
The important detail is the required enemy count already being met. That is the condition named in the developer's note. A mission with an unfinished objective, a missing tutorial achievement, or another kind of progression problem is not automatically the same bug.
Compare what your mission is asking for with what has actually happened. If you are reporting the problem, note the mission name, installed version, remaining objective text, and whether the required enemies were destroyed. These observations make it easier to distinguish the documented issue from a different blocker without guessing at a workaround.
The official S.O.N.A.R. announcement feed contains the 1.0.2.0 changelog and is the appropriate source for checking later fixes. The available note does not support claiming that restarting, destroying extra targets, or changing hosts is a confirmed cure.
Keep the tutorial achievement separate
The same patch changes when the tutorial achievement unlocks: it should be awarded upon completing the tutorial rather than after the first mission. That is a separate correction in the changelog.
If your tutorial appears finished but its achievement is missing, compare that behavior with the achievement change. If a combat mission will not end after its enemy requirement is satisfied, compare it with the mission-completion fix. Sharing a patch number does not make those two symptoms interchangeable.
FAQ
Is there a confirmed fix for missions that will not complete?
Yes. Version 1.0.2.0 addresses a rare issue where some missions failed to complete after the required number of enemies had been destroyed.
Does that patch fix every possible stuck mission?
The changelog does not make that claim. Its stated scope is the enemy-count completion issue, so other unfinished objectives or symptoms need separate investigation.
Will updating recover a mission that is already stuck?
The official note does not specify what happens to an existing stuck session. It confirms the fix without publishing a session-recovery procedure.
Is a missing tutorial achievement the same problem?
No. The tutorial achievement has its own 1.0.2.0 correction, changing its unlock point from the first mission to completion of the tutorial itself.
