For example https://modrinth.com/mod/pineapple-delight/version/RqiuTl9x only supports 1.21.1 but it mistakenly has 1.21.1-1.21.4.

On a similar note, the fabric.mod.json could use some improvements:

• The Minecraft dependency should be exact. For the 1.21.1, it should be 1.21.1.
• The another-mod suggestion should be removed
• The farmersdelight dependency should be added

You re right! I'll changed them, and thanks your suggestion!

You have also not made the other two improvements to the fabric.mod.json that were requested

https://modrinth.com/mod/pineapple-delight/version/1.0.9 still has incorrect metadata
