Unluckly, the issue is still there, it started when i added your mod, when i deleted it, everything worked as it should so please check it out. Here's the quick footage of the issue https://www.youtube.com/watch?v=j-CW3e7PrZ4

Can you provide additional information such as modloader, mod list, mod version, etc. following the issue template?

I've done it in pastbin since i had to crash minecraft to copy my mods, here is i think everything you need: https://pastebin.com/3h2LFQcd

To prove this is an issue with our mod, you need to be able to give us the steps to recreate the issue in a new world with only More Villagers installed -- no other mods and no Optifine. If the issue still occurs in a new world even after uninstalling every other mod except for More Villagers, then we can look into it. But as of what you have provided now, there is no evidence to suggest that our mod is the cause for this.
