I received the quest, confirmed that I had the new travel location, but I had some randomly generated quest i wanted to get some work done on first. About 4 combat screens and 2 turns later I'm ready to do this quest, only for the location to have disappeared from my list. I assume this is a bug and not a quest fail state because the quest is still considered active. Would there be anything  I could do to get it to reappear without loading a save before receiving the quest? 

Love the fist game, and this one too so far. I admit I miss the capture mechanic from the first game, but i am enjoying combat more in this one. Thanks for all your hard work, and hope this can be of use.

If your location has been removed it won't appear again, although I don't get what could go wrong from your description

Sorry for the false report, I loaded an old save file and got back to this point. The location had a forget location button and I had most likely hit that on accident. For some reason I had thought quest locations didn’t have a forget button until the relevant question was completed/failed, my bad.
