Who knows, but maybe the PC and others thought that their wouldn't be a significant delay because of machinery issues.

But because it has delayed the milestones longer than they had anticipated, they thought it would be prudent to let the shareholders know that some issues did exist with some of their machinery and now these issues have been remedied.

The important thing is that nothing has materially changed with their anticipated Milestones, just a delay. To put this news with the financials is brilliant. Kills 2 birds with one stone.
