Mod version: Hextorio 1.5.10
Planet: Nauvis
What the game tells me in the item catalog :
"Electrocute an enemy unit near a trade involving this item with at least 85% productivity."
What I did:
The item is part of this trade (either as input or output — I tried both ways).
The trade shows exactly 85% productivity
I killed biters / spitters inside the same hex where the trade is located.
I used only electric damage sources:
Tesla gun
Tesla destroyer drones
Personal electric discharge defense
Result:
Nothing happens. The item stays at silver star. No progress bar appears, no message, no rank-up.
I also tried buying/receiving the item multiple times in high-productivity trades — still no change.
