1.2.1: [Launcher Description] Mod in launcher info listed as "Unknown by Unknown"

[einsteinsci]

Version:
1.2.1

What is the bug:
In the launcher description for DW20 1.7.10, near the bottom of the mod list is a mod listed as "Unknown by Unknown". Clicking on the link yields a NPE in the log. There is no mod in the actual mods folder titled "Unknown". Not sure if this should be posted here or as a bug with the launcher, but I thought since this is specific to DW20, it should go here.

Mod & Version:
"Unknown"

Paste.feed-the-beast.com log:

Can it be repeated:
Yes. Just open the launcher and see for yourself.

Known Fix:
Figure out which mod(s) is/are labelled as "Unknown", and edit the modpack description to show what the mod(s) actually is/are.

If your using the curse launcher then it probably has to do with a mod that you can't download from curse as that is how the curse launcher determinants which mod is created by who.
