I am playing OOT and am now trying to catch the 10 big poes to get my last bottle. However, despite the fact that I trigger the exact areas where the big poes should appear, when I defeat it, catch it and bring it to the poe shop, I always get told it is just a normal poe. Also, on these spots the poes reappear, whereas it would sound more logical to me that the big poes would not appear again.
Can anybody tell me why I don't get the big poes? Is it some bug maybe? I seem to have an early version anyway because the fire temple tune also has the muslim chanting, and I know that the later released versions didn't have that.
