Need advice, Zoysia Z-52 Sod dying?

I just laid 120 square yards for a client about two weeks ago. The ground was prepared properly but for some reason, the very last few squares laid are turning brown. The sod was all cut at around 10 am and laid by 6pm the same day but this area was the last to go down. The rest of the lawn looks great and is already taking root, and the other pieces of sod from that pallet are looking fine.

I Thought maybe it was soil contact or lack of water, so i rerolled the area a week ago, hand...
