Troubleshooting

Client does not load in-game

Sigma historically targeted Forge profiles. Ensure Forge is installed for the correct Minecraft version and that the .jar is in the correct mods folder.

Minecraft crashes on launch

Check for conflicting mods. Historical builds may not be compatible with modern mod loaders. Check .minecraft/logs/latest.log for errors.

Keybinds do not respond

Sigma's keybind layout differs between builds. Review the config file or rebind keys from the client menu if it opens.
