Sorry to hear that you're having issues with pre-ordering the game. If you cannot pre order then that means that the feature is not available in your region. I wouldn't recommend doing the pre order from a different region though as you may experience
download issues with the game.
As for the map your best bet would be to contact the developer to ask them about purchase options as only they will know if it will be release publicly in the future. I would presume so though as, if they don't, only those that pre ordered the game will
have access to it and that wouldn't be fair to those that didn't.
Did this solve your problem?
Sorry this didn't help.
Great! Thanks for marking this as the answer.
