panic: runtime error: index out of range

Describe the bug

With Mangadex, I'm getting a ton of failed downloads (originally encountered in Kaizoku but the same when running mangal directly) with errors like this:

 mangal inline --source Mangadex --query Tengoku Daimakyou --manga exact --chapters 135 -d
panic: runtime error: index out of range [16] with length 16

goroutine 1 [running]:

Curious if this is a problem with Mangadex (I've confirmed X chapter does exist on the site), or a mangal known bug.

Reproduction steps

mangal inline --source Mangadex --query Tengoku Daimakyou --manga exact --chapters 135 -d

Expected behavior

Chapter is downloaded

Additional context

Running via homebrew on macOS, same behavior in Kaizoku via docker

Operating System

macOS
