forge-1.9.4 mod works in mdk, but not in installed forge

[neonic148]

I have a crash that occurs when I run a mod from forge-1.9.4-12.17.0.1976 installed with the windows installer. It's about a method that's supposed to be part of minecraft. Strange thing is that I had this same mod running from a "gradlew runClient" using the mdk forge version 1.9.4-12.17.0.1976 and it ran fine.

 

What am I doing wrong?

It looks like you're using a deobfuscated build of the mod in the obfuscated environment. Make sure you build your mod with the

build

Gradle task, this reobfuscates the mod after building it.

gradlew build seems to fix it. Many thanks!
