Thanks.
Unfortunately 2.13 introduces other issues related to writables so I had to roll back our agent to 2.12.1 until 2.13.3 comes out.
damned if you do; damned if you don't.
Appreciate the heads up though.
I also took the 1709 update so I'm just going through the motions now so i know how to test to make sure the things are fixed when they say they're supposed to be fixed.
