It has been several years since I played TTG, so maybe I did something wrong.  My scouts found the chests and opened both and I even saw the masking cloak, but it did not go in the my Treasures.  I built the temple, went to Lonely Iceberg and tapped the Scout Lodge and was told I surely needed the masking cloak, but no scouts appeared or went swimming.  Also, in the same strange vein, I went to 2 other islands that were supposed to have sharks between 2 islands and needed the harpoon, but scouts swam to the islands, got the gems and no sharks appeared.  What have I done wrong and do I have to start all over again.  Feel like a klutz.  Thanks for any info anyone may have.
