I had to scrap eatmanga because they operate some sort of fail2ban for a few hours if you go too quickly. I need to figure out what the too quickly part is, as a backup to the new site. I found goodmanga.com allowed for a similar setup to work, but less fussing over formatting.
I accidentally overwrote the correct values of the json file. Put back to right
Didn't realize a change I made didnt require me to go back 2 chapters for the saving of the name anymore. changed back to -1
