Running Forge .473 (latest I believe) MC 1.4.6 and 50 odd mods I am getting some console spam in the Multi-MC console it is also in the Forge log, sample follows

 

2012-12-23 13:43:03 [sEVERE] [ForgeModLoader] The mod BuildCraft|Core is expecting signature null for source buildcraft-A-3.3.0.jar, however there is no signature matching that description

2012-12-23 13:43:03 [sEVERE] [ForgeModLoader] The mod BuildCraft|Energy is expecting signature null for source buildcraft-A-3.3.0.jar, however there is no signature matching that description

2012-12-23 13:43:03 [sEVERE] [ForgeModLoader] The mod ExtrabiomesXL is expecting signature null for source ExtrabiomesXL-universal-1.4.6-3.7.0a.jar, however there is no signature matching that description

 

I get one line for every mod I have installed (hence it's a sample my console log and forge log themselves are kinda big), just asking is this ignorable since it is flagged as a severe warning?

Blame FML for trying to get every mod to sign their files.

Is that a problem lua?

Is that a problem lua?

No, that isn't a problem (to me at least).

Though it would be nice if that was toggleable...

Im having the exact same problem? can't anybody help?

Leave it alone, leave it alone, it's just monsters in your dreams...
