I can't be the first to be in this situation: I started my single player world and before I made any progress in the quests, I joined a friend's world and completed some of the quests there, unlocking the FTL drive and navigation and Ark stores.
Now, back in my own singleplayer universe, my ship's FTL drive is working and I can view navigation but can't actually go anywhere. I had to reactivate the Ark gateway on my planet in order to get there, but all the stores are boarded up as if I hadn't completed the quests. (The quest log is up to date with what I completed on my multiplayer world: the Floran scanner quest.)
Does anyone know how I can unlock the stores since I can't redo the quests?
