Thank you for helping with the project! Your reports are appreciated!

Testing on a minimal instance with version 0.3.2, the knives are enchantable with Looting.

I see you have some mods that also introduce knives, such as Aquaculture. Make sure you're actually trying to enchant a knife from FD (they have a curved blade edge). If you are, some other mod might be interfering with enchantments.

Damn.. I'm not sure what is causing it then because I have made sure I'm using the farmer's delight knives :(

Your modlist is rather large, so testing one by one might not be feasible. Still, try making a minimal instance and re-adding the mods in batches to see if the issue goes away and/or is caused by something in there.

Are you playing on a premade modpack, or is it a custom instance?

It's a custom pack I made, and yeah there's a lot of mods so it'd be a pain to try and track it down :/ Tbh I guess I'll just try to enchant it with the command. (that didn't work lol)
Sorry for taking your time. Thanks for the responses :) I really love your mod, keep up the great work!

What you could do to troubleshoot more easily is do a "binary search":

• Remove half of all mods except FD and try enchanting again:
  • Did the problem persist? Cut the mod list in half again until it goes away;
  • Did the problem go away? One of the removed mods is the culprit; try sifting the ones you removed.

Unfortunately, I could not replicate the issue on my own end, sorry. I'll close the issue for the time being, but feel free to post/reopen if you manage to detect something new!
