Im on the Look for clues at the squid quest and i did the part where i looked at the book and in the objectives it says that the book is found but it didnt give me a new quest. It also says complete with old fisherman but when i talk to him still nothing happens. Is there a way to fix this or to reload the quests?

1. try exiting minecraft and restarting (NPC quests can glitch from time to time but usually resolve on their own with a reboot).
2. go back to book location in in squid, be sure to stand right next to book
3. if these don't fix join discord and provide some screenshots https://discord.gg/HZgrxSm
