Let's talk about "Mod Errors"

Hello,
I don't know if anyone else has experienced this issue, but I believe there are hundreds of thousands — maybe even millions — of players who use Minecraft with mods.

There’s one problem that really frustrates me: when I download a mod from CurseForge and it conflicts with another mod, the game simply shows an “-1” error. That’s all.

It feels like going to a doctor, saying “my leg hurts,” but the doctor doesn’t tell you what’s wrong.

Why can’t the error system provide more detailed information? For example:
[Mod Name] and [Mod Name] are conflicting.

Even a small code addition like this would save players hours of frustration.

Thank you for considering this feedback — I really hope this kind of diagnostic feature can be added in future updates.
