An unofficial compatibility patch for Create: The Factory Must Grow (TFMG) that fixes the Converter block across every current TFMG branch, TFMG 1.2.0, TFMG 1.2.2+, and TFMG Community Edition, and adds its own Converter block on the versions that no longer ship a usable one.
On TFMG 1.2.0, the Converter block (which converts stored FE into TFMG's own electrical system) could get stuck permanently showing:
U = 0V
I = 0A
Network Power Generation: P = 0W…even with a full energy buffer and a valid, connected electrical network. This happened regardless of how much FE was stored or how the network's resistors/consumers were wired.
On top of that, TFMG 1.2.2 and later removed the Converter block entirely (the classes are still buried in the jar, but nothing registers them), so anyone on a modern TFMG version had no way to bridge FE from other mods (Create: Crafts & Additions, etc.) into TFMG's own electrical network at all.
Digging through TFMG 1.2.0's electrical network code, the 0W bug turned out to be a timing bug: when the electrical network updates, it checks the network's resistance to decide whether the Converter is allowed to generate voltage, but the resistance calculation was scheduled to run later than the check that depends on it. By the time the resistance was actually calculated, the voltage-generation check had already run and locked in "0 output" for that pass, and nothing ever triggered a fresh check afterward. The Converter was stuck reporting zero output indefinitely, even though the network itself was perfectly valid.
On TFMG 1.2.0:
On TFMG 1.2.2+ and Community Edition:
Automatic detection, zero configuration: the mod identifies which TFMG variant is loaded by reading class bytecode (never by loading TFMG's own classes), so it applies exactly the right behavior for your setup with nothing to configure. This also means it will automatically stay out of the way of any future TFMG build, official or a fork, that ships its own fix or its own Converter.
None of this changes TFMG's recipes, balance, or content, it's purely a functional and compatibility fix so the Converter behaves the way it's supposed to, on whichever TFMG version you're running.
This is a patch/compatibility layer, you still need to have Create: The Factory Must Grow installed (any of 1.2.0, 1.2.2+, or Community Edition). This mod adds the missing behavior on top of it and does nothing on its own.
This mod was originally built to fix a bug found while developing [Cobblemon + Create - Pokémon meets Industrial Revolution!], my own modpack combining Cobblemon and Create with 300+ mods. That said, it's a general-purpose fix for TFMG itself, there's nothing pack-specific about it, and it should work fine in any modpack or standalone setup that includes TFMG, on NeoForge 1.21.1.
