Dang! Thank you for letting me know. Thought we'd sorted out that issue but apparently not! All I can suggest is emptying your cache, but if that doesn't work, you can get a physical copy via RPGTrader: https://rpg-trader.com/products/1584/a-fruit-moon-for-bugworld
I'll try and get the issue sorted as soon as possible. Thank you again for the head's up!
UPDATE: It might be accessible again now. Honestly, this issue has been popping up erratically for a while and we've pretty much done all we can do on our end.
