[Genhis][2.0.73] expansion_shaders feature flag causes additive-soft glow to fail

[Shemp]

Apologies if this is a duplicate, this is a very specific bug that I've managed to confine and I didn't know what other users might call it.

First, load the game with only "base" mod (I had Elev. Rails and Quality in my test but I think it's irrelevant) and this debug mod:

The mod alters the LED on the electric mining drill to use "additive-soft" blending mode. At night time it looks like this:

The glow doesn't work if you activate the "expansion_shaders" feature flag. You can do this manually in info.json, install the "Enable all Feature Flags" mod, or load Space Age.
