The F1 bug will be fixed next maintenance/hotfix patch. (For now I recommend Alvida. I personally always go there at Lv. 20 anyway and recommend it to everyone else as well)
The way this bug came into existence was that the mission was my testing ground and I ended up forgetting removing those stats from the mobs (oops!).
As for the not being able to return from old pow issue, I am going to set the price for the teleport card in the cash shop to 0 (writing this I have already done so). The tp card does not vanish after usage hence it used to be 500 cash as it meant "free" travel forever on that character. The continent is mainly there to be debugged in general, portal issues and so on until I make a more complete implementation with quests, NPCs working, more visual details and all that good stuff.
