when does .6 come out for free and how do i complete the fisherman quest?
Then when 0.8 comes out, then 0.6 will be free.
You need to kill the spiders in the cave and for the spider thread to fall out. If you haven't reached it, complete the rest of the quests.
i got it didnt see that it needed three string
Yes. But the spider cave is not available at the beginning of the game. Just play on and you will open the cave.
