Hi! So sorry this is happening :/. I've seen this problem before with other packs, and it usually happened when the pack price changed (this pack is now 5 and the crop is 3). I'll look into how to fix it and get back to you with an update. (Thanks for your support btw)

Thank you so much for the help! Unfortunately, I'm still only seeing GHBP Demo V1.8.zip available when I click "Download". Wonder if itch.io is considering GHBP_Premium_V2.5.zip as a new file that I don't have access to, rather than an updated version of the existing file? (the version I had previously purchased and downloaded was v2.0)
