If you click on one of the mods when it is downloading several mods, and then it updates a mod it is currently downloading, the previously selected mod turns blank.
Steps to replicate:
1) Select all mods to update and click the update button.
2) Move the mouse to one of the entries in the mod list (somewhere in the middle of the list).
3) Hold the mouse still until the current mod finishes updating and the list moves up.
4) The previously mouse highlighted mod's text turns black (hardly visible against the dark grey background) when moving up instead of being white like the rest.
Note: If we move the mouse over the bugged entry and off again, the text becomes white.
