The latest versions of forge and neoforge do not recognize the modid;

The logs say:"

[19:01:37] [main/ERROR]: Invalid modId found in file E:\minecraft\Minecraft1.20.minecraft\versions\1.20.1Forge\mods\alternate-current-mc1.20-1.7.0.jar - alternate-current does not match the standard: ^[a-z][a-z0-9_]{1,63}$

Thanks for the report. I accidentally changed the mod id when updating to the new MDK. Its a simple fix but it'll have to wait 'till I get back home, which could be a few days.

I uploaded patched versions to both Modrinth and CurseForge, that fix this issue
