I am trying to create a mod which supports multiple forge versions at the same time (but only for one root version)

These are the relevant things of mod.toml:

loaderVersion="[33,36]"
version="${file.jarVersion}"
[[dependencies.examplemod]]
    modId="forge"
    mandatory=true
    versionRange="[33,36}"
    ordering="NONE"
    side="BOTH"

[[dependencies.examplemod]]
    modId="minecraft"
    mandatory=true
    versionRange="[1.16.2,1.17)"
    ordering="NONE"
    side="BOTH"

And these are the relevant things of build.gradle:

buildscript {
    repositories {
        maven { url = 'https://maven.minecraftforge.net' }
        mavenCentral()
    }
    dependencies {
        classpath group: 'net.minecraftforge.gradle', name: 'ForgeGradle', version: '5.+', changing: true
    }
}
minecraft {
    // ...
    mappings channel: 'snapshot', version: '20200514-1.16'
    // ...
}
dependencies {
    minecraft 'net.minecraftforge:forge:1.16.2-33.0.61'
}

You can find the console error log here:

in 1.16.3 the world gen has changed, this is not possible specifically in this version spectrum(1.16.2 - 1.16.5)

My code is only Entity and Keycode specific, it does not contain world generation

So what you are saying is that I should only make my mod for like 1.12.2, 1.14.4, 1.16.5, 1.17.1, etc?
