The recode for v1.13 is about 60% completed so far. I've been busy in my daily responsibilities. I have mostly stopped playing minecraft and I have lost a lot of motivation to continue developing minecraft plugins. These are some reasons progress is slow. Please show some support if you wish the plugin to be updated. Even just a reply on the discussion would show that that you want the update. If a good amount of people want the plugin to be updated to 1.13 than I'll be more motivated and devote more time to doing so.
Thank you.
