Okay I have no idea on what is actually happening, because I only read this one function, but what I think is the error: https://github.com/metafates/mangal/blob/main/inline/options.go Line 110: from = util.Min(from, uint64(len(chapters))) should actually subtract 1 ? Just a shot in the dark really...

Line 110:

Actually, that might be the case, lol

Wanted to add a few more samples: Helck_chapter#405 Helck_chapter#395 Helck_chapter#440 [Oshi_no_Ko]_chapter#142 [Oshi_no_Ko]_chapter#238

Have a decent number more if there is a way to export my Bull Dashboard.
