The v1.0.13.0 boss rebalance remains relevant, and v1.0.16.0 still lists enemies falling through the floor as a Stage 4 progression blocker.
Stage 4 changed materially in v1.0.13.0
Patch v1.0.13.0 changes the final-boss fight and the general berserk rules used in Stages 3 and 4. Bosses are no longer fully invincible during berserk, their damage reduction is lower, and their HP is higher to compensate. The berserk camera zoom now triggers only once. In Stage 4 specifically, the final boss no longer recovers HP, the slow-zone spawn pattern was adjusted, and projectile drop patterns were improved.
The same update fixes abnormal slow-debuff stacking during the final boss, true-ending dialogue and lingering effects, missing music after the true ending, and several prior stage-edge cases. Patch v1.0.16.0 still lists one blocker: enemies can fall through the floor in Stage 4 and prevent progress. If that symptom appears, capture the version and scene instead of rebuilding around a bug.
Relearn berserk
Bosses remain damageable during berserk, but the rebalance also increases HP.
Drop old healing advice
The Stage 4 final boss HP-recovery mechanic was removed in v1.0.13.0.
Read the new patterns
Slow zones and projectile drops changed, so pre-July 29 positioning advice may be stale.

v1.0.16.0 still lists enemies falling through the floor as an official Stage 4 blocker.

FAQ
Are all Stage 4 blockers fixed?
No. v1.0.13.0 fixed several final-boss and true-ending cases, but v1.0.16.0 still lists enemies falling through the floor and preventing progress.
What changed for the final boss?
HP recovery was removed, the slow-zone spawn pattern was adjusted, projectile drops were improved, and abnormal slow-debuff stacking was fixed.
Can I damage the boss during berserk?
The official notes say Stage 3 and 4 bosses are no longer fully invincible during berserk. Their damage reduction is lower, with higher HP added to compensate.
Should I change my build after a stuck state?
Not first. Confirm the version and compare the symptom with the current known-issues list before treating it as a strategy problem.
