Logic-based mods do not work while skin mods load correctly (Sonic Frontiers 1.42, PC)

[nour9264]

I am using Sonic Frontiers on a standard Windows PC (not Steam Deck) with game version 1.42 and the latest version of Hedgehog Mod Manager. Game file integrity is verified with no issues, antivirus and real-time protection are disabled for testing, and both the game and Hedgehog Mod Manager are run as administrator.

Skin-only mods load and function correctly, confirming that basic mod injection is occurring. However, logic-based mods that rely on gameplay, animation, or transformation logic (such as Super Sonic or Shadow mods) do not work correctly. No transformations or gameplay logic changes trigger, and there are no crashes or error messages.

More specifically, when using Shadow, the boost behavior is clearly broken: the boost speed is not properly scaled and behaves incorrectly instead of the expected controlled boost. Additionally, character-specific logic does not seem to apply, as the cyloop remains blue (matching Sonic’s default behavior) instead of turning red as expected for Shadow.

Transformation logic is also affected: pressing Up on the D-Pad while jumping, which should trigger the Super Sonic transformation, does nothing and no transformation occurs

A short video demonstrating these issues is provided below for reference.

Have you confirmed all those mods are designed and tested to work on the build you are playing on? Have you tested if codes work?

yes i did, and the strange thing is that when I downloaded the game, they were working fine, but after I restarted my pc it no longer does, even tho i tried everything like reinstalling the mods and the game

after inspecting the mods themselves, the .hmm files clearly contain the correct runtime logic (animation speed, boost parameters, style gauge color, transformation logic). This suggests the mods are being loaded, but the .hmm runtime scripts are not being executed in-game.

Since visual/asset-based mods apply correctly while all logic-driven behavior does not, this looks like a partial injection state where asset loading works but the runtime execution path for .hmm scripts is not being called.

This affects input-driven logic as well (e.g. transformation input not triggering), not just animation values.

Sounds like an issue with the compiling or loading of the codes. Can you confirm all mods with no .hmm but with .dll work?

Also have to checked the latest Actions build? The latest build on the Releases page is currently very outdated.
