Today Borderlands 2′s latest patch was released, and while it included some obvious additions such as the Mechromancer class, and support for it, it also packed some other fixes and additions.

Some of my pending side missions are listed as "Blocked" instead of where they take place, and I can't select them as my current mission, but if I go where they are I can still do them. Not sure if this is a result of the patch or something I did, but it didn't happen before the patch.
