After updating to version 0.76, I lost all my recall.

Sorry for that :(.
Let me know if it happens again, which would indicate a persistent bug and that would be very problematic.
EDIT: I just remembered, did you update from version v0.70 to v0.76 ?
If that is the case, loosing the recall collection is intended as the save updater will convert your save from 0.70 to 0.75/0.76 and the old recall gallery system was not compatible with the new one, so the updater clears the data.
