Outbreak not completing

[scotskevin]

Finished all the objectives in the quest outbreak, but the quest would not complete.

Anyone else experienced this, and if so, any workrounds?

Known issue, you likely killed a boss before triggering the objective to do so.

It should be fixed next patch.

Workaround:
Do left side first, then right. When you do final boss be sure to run all the way up to where he spawns before you engage him.
