Have you done the rest of the missions leading up to The Vault? It doesn't matter now if you are at the min level. You must either 1) go through the Episode chain or 2) skip the Episodes you dont want to do till you get to The Vault.
It's more like a "funny, creative typo" thing. I remember someone who wrote "Bier Patch" instead of "Briar Patch", well I'm German and "Bier" is German for "Beer" so I found that spot rather tasty...
Going by CrustyMac's confusion and my first thought when I read "frong quest" he probably just wondered "what frogs?"
Frogs and beer... hmmm somewhat French-German combination... - I go with the German part .
Could it be that the min level for quests has changed? I logged on after 2 months or so, and I see SO many things changed. For better, I might add. I'm really enjoying STO more and more, but some of the older quests seem to have higher required level. So i.e. I could do the first mission for the Deferi, as I had it in my quests already before, but I couldn't get another one in quest line, as I apparently need to have higher level.
Correct me if I'm wrong, though. As said - I haven't played for a long time, so I can be wrong .
