I just finished doing Spire of the Watcher solo on Explorer, it tracked me completing the first two encounters but did not track the defeat of Persys, Primordial Ruin, thus being unable to progress in both quests.

Explorer mode is tutorial mode. It's for learning not earning as it's easier than the standard version. The only thing preventing anyone from finishing it is, quite literally, the player bc there are zero wipe zones. Why should players get final rewards for beating a tutorial?
