When the athletic dragon quest ran out of time (I did not manage to breed it in the 2 weeks I tried with was veeeeeery annoying) there is an option to buy the Nether Portal for 24 gold. I had enough so I decided to purchase it and it did the cute dragon loading screen but I never got the portal, it did however take my gold.
There is an option to buy it in the marketplace but only if I reach "level 1000".
Is this a bug or...?
