Android Museum Rearrange option stops working after donated item disappears

[snowchan]

I encountered a bug where an item that had already been donated to the Museum disappeared.


I am confident that I donated my Prismatic Shard during the first year, before I knew about the Galaxy Sword (the shard was placed directly above the Starfish, as shown in the screenshot). Today, when I checked the Museum, the Prismatic Shard was missing. This also caused the “Rearrange” option in the Museum to stop working.


After that, I checked my storage at home, and the Prismatic Shard was in its original state, showing the description:

“Gunther may tell you more about this if you donate it to the museum.”

I then donated the Prismatic Shard to the Museum again, and the “Rearrange” option started working normally.
(I did not re-check the shard’s description again after donating it while writing this post.)

I am not sure whether the originally donated Prismatic Shard returned to my inventory or not. I only noticed that the shard was missing from the Museum.

I know I've had instances where I accidentally pick up one of the already donated items after placing a new donation. As long as that now not-donated item is in the backpack, I can't rearrange the collection, but when talking to Gunther I get the option to donate. Could that be what happened to you?
