Android 5.0.2

latest version of Fallout Shelter, auto-updated from google play

When the game updated, I had the following objective active and mostly complete:

Raise SPECIAL stat of 47 dwellers

(completed 45/47)

After the update it appeared to function normally, however when the daily bonus came along, I chose a different objective to skip (for the obvious reason). When I did, the progress counter on this objective reset. Worse still, after it reset, dwellers that I had previously raised up to count towards this objective the first time were not counting toward it again. E.g., it remembered that I had already raised a SPECIAL stat on these dwellers, so it wouldn't let me use them to raise another stat toward the same objective.

P.S. tried to link a screenshot but forum won't let me.
