One hour before a deadline, one of my team members notified me he had completed his task and signed off. The only thing left to do for me was to merge our branches and submit the code for review. This was supposed go smooth with only a few changes made. But for some reason the build kept crashing and this ONE hour before the deadline and no way to reach my team member... This was a stressful situation to say the least.

And yes I am aware that you are not supposed to be merge branches one hour before deadlines.
