Hi! I did not see any report about this, but I found out that unlocking "Galvanization tech card" unlocked respective data twice and for some reason also unlocked golden tech data recipe. I looked at the compat file and on line 299 this should be "golden-science-pack" instead:
local golden_tech = data.raw.technology["galvanization-science-pack"]
Also right after this is registered twice, which leads to the double icon unlock:
table.insert(galvanization_tech.effects, {
type = "unlock-recipe",
recipe = "outer-rim-galvanization-research-data"
})
I made the changes locally and now the technology correctly unlocks only the relevant recipes and only once. This is really a minor thing, but I was a bit confused initially about the extra recipe.
