Your English is fine and the fix works.. Thanks! :) Added in v1.0.37.
dynasty-scans bug.
A bug in the script on some pages. If the number of pages in the title is more than the total number of pages, the script does not work. Example http://dynasty-scans.com/chapters/sayuris_little_sister_is_an_angel_ch02.
The decision to fix curpage: return parseInt(getEl('#image > div.pages-list > a.page.active').getAttribute('href').substr(1))
Sorry for bad English.
