You're currently on v0.6.25, but your progress is still at around v0.6.10/0.6.11. When several updates have been skipped, you need to trigger the update that comes immediately after the version where your save stopped.
In your case, assuming your last completed update was indeed v0.6.10/0.6.11, you first need to unlock the v0.6.15 content by doing the following:
How to access the update: (Load a save from the point where the previous update ends — specifically after meeting Lucy and having the hallucination with her in the alley.) ⚠️ Important: This only works by loading a save, not through the gallery.
It doesn't matter that you already have v0.6.25 installed. What matters is your save's progress. Since your save stopped at v0.6.10/0.6.11, you only need to meet the requirement to trigger the next update, which in your case is v0.6.15.
