Issue
The quest of making a flint battle sign on the Tinker's Construct chapter shows "Completed" on both the flint tool rod and the flint sign but the "Claim" button remains greyed out. On the overview of the chapter, it show me as only 1/2 completed, Edit: Actually crafting the battle sign completes the quest, but it is not mentioned in the quest requirements.

There is more than one page :)
There's a little button on the right hand side near the bottom of the task panel.
