I too am having some serious problems. I only play on Kongreate and have no facebook account. I do have creds but I will not spend them until the problems are fixed.
There is a guard blocking the training area surrounded by the metal fence.
My mailbox doesn’t work so I can’t recruit friends.
The boat on the docks redirects me to facebook and logs me out of kong.
Aerobia won’t let me enter.
The travel agent won’t let me travel without kreds and until the other issues are resolved I will not spend them.
Other than the problems I love this game so please take a look at these issues and resolve them so us non FB users can enjoy it too.
