multiple fishing challenge failures

to clarify, I stayed until the end of the challenge, but did not talk to Derris, and then came here to report the bug.

Fishing can be tricky, and requires patience. Fish will generally only be attracted to bait in front of them; that might be where you're going wrong.

Closing issue: This isn't a bug, fishing is verified working as intended.
