GW reverted back to pre-update state? (MERGED THREADS)

Yup something happened from node 6 to 9 was a lot harder than it usually is. And on the last node i had to face level 73 toons but with only protection on two of them. My toons are only 60 max i have one at that level rest are 57 58 and 59. I was like what in the world is going on.
