Hi! Three small things in 1.0.42.

1. ske_water_vaporization and ske_ammonia are unlocked only in the branch for "no Skewer Planet Vesta" (prototypes/technology.lua:744-825). Vesta is a required dependency, so that branch never runs, and the Vesta branch (668-744) leaves them out of chunk_slurry_creation and alternate_methods_of_production: nothing unlocks them.
2. The oxide slurry recipe is called nitrogen, like the fluid. Mods that handle fluids by name hide it and strip its unlock (paracelsin-krastorio-compatibility-plus does); a ske_ prefix would avoid that.
3. prototypes/planet/tiles-primalshattered.lua:183 redefines Space Age's tile-effect space as {shader = "space", space = {}}, which drops its scroll_factor = 0.15 (the default is 0.25) for every space tile; a separate name would keep both.
