[VISUAL] $Bumpmap2 doesn't render ( LightmappedGeneric / WorldVertexTransition )

[WhiteRedDragons]

Describe the bug

An issue in the cpp or fxc of the shader causes the second bumpmap to not appear.
Why? I don't know the shader is incredibly convoluted and I can't tell from a quick glance.

Additional context

Probably related to many other graphical issues that might have been reported in the past.
Cief reports this shader behaviour also happens on stock shaders

Cief also presents the contents of a VMT on which this issue has been seen
Seamless Scale is potentially not the cause of the issue as it happens without it as well.
$BaseTexture, $BaseTexture2, $BumpMap, $BumpMap2, $BlendmodulateTexture, $Seamless_Scale

Lines 450 and 651 in LightmappedGeneric_dx9_helper.cpp are for the flashlight shader. SDK_lightmappedgeneric_flashlight_ps2x.fxc line 61 loads NormalMap2 from sampler 6. There was no issue here.

You are correct, we realised this on the map labs discord, I will adjust the issue's name.
Now it baffles me as I cannot find a reason for $bumpmap2 to be broken then
