If my player board is full on pack birds which all have treasures under them, can I visit the stables and buy a tortoise to replace a pack bird? If I can, do I lose the treasure under the pack bird when I flip it to the tortoise side, or do I just flip the bird over to the tortoise side? I’ve looked in the rules for this and can’t find it. Maybe I’m just missing something. Any help is appreciated.
I didn't find the right solution from the Internet.
