Oh dear! So sorry for you losing all that progress 😭 thank you for playing our game for so long!
Fabled/legendary resources are definitely the big endgame grind, and the business bluebird was meant to help alleviate it a bit, but I implemented his quest wrong... I notice the quest only says he's going to reward you with 10 *fabulous* ore, when it should be 10 of each legendary resource... this was a problem I noticed like half an hour before the jam deadline, and I thought I uploaded a fixed build. He's totally scamming you in this build... my last minute change didn't make it in for some reason! Sadly I did not have time to playtest this change in full on itch before the deadline...😅 please forgive the bluebird's transgressions 🙏
There's a dedicated farming spot for each legendary resource at the "end" of each section of the world, with a lot of nodes near each other, so the ore one would be the best spot for grinding legendary ore (there's enough to gather forever without waiting for respawns). It does take a long time even still though, especially for a jam game; we fell a bit short on time in the end, and playtesting a full run took so long!
Once the jam voting is over, I'd love to revisit this project again 😁 especially to implement a proper ending for the dedicated players like you 😉 the silver lining is you didn't miss out on too much, aside from the satisfaction!
Thanks again and I'll be sure to check out your submission too!
