Particle shader breaks precipitation occlusion on recent test builds

On all test builds from at least as far back as early August, precipitation occlusion is broken whenever replacing the particle shader. Toggling on/off or otherwise changing any other settings don't affect the behavior. Tested on vanilla load order for 1.5.97 with only CS and Address Library active. When testing on the Nexus release with every Nexus feature active with same minimal load order, the particle shader is replaced by default and precipitation occlusion works perfectly fine. Using RTX 2080.
