Hey Sam,
I checked into this on your behalf. It seems that despite the earlier conversation between yourself and the Battlegrounds staff they received orders well after the deadline. Since we are well into the first week of the Hammerblow, I'm afraid that nothing can be changed now. Allowing you to make planetfall would retcon a lot of actions on behalf of other players and while we would like to be generous to players whenever we can, we also have to consider when that generosity would be unfair to other players.
While its unfortunate, I do feel the decision is fair. All of the other players have repeatedly been able to submit moves to us and those who did not simply did not move. This is true even of players who were an hour or under late with their submissions and since we were strict with them its only fair of us to be equally strict here. Even if it was previously unclear what you needed to do in order to get back into the campaign, after the prior conversation with the staff still we received moves too late. I'm afraid there's simply nothing to be done at this point.
Sorry Sam, but efforts were made to help you on this. I back Battleground's decision here.
