Path Mapping Slash Conversion

Greetings fellow sailors on the good ship SS Deadline. Just read the maintenance mode thing. We’ve just hit an iceberg havent we…
Anyway I have an oldie (style) but goodie. Nuke 16.0, Deadline 10. 4.1.10, path mapping…

Its changing the beginning of the path but not changing the remaining slashes. eg:

"/Volumes/pdgwipin/test/VFX/FOR RENDER TEST/Script/Test_01.nk" with "C:\Volumes\pubprodin\pdgwipintest/VFX/FOR RENDER TEST/Script/Test_01.nk"

Looking at the other examples of path mapping issues, I didnt see anything this recent so I thought this had all been fixed/locked down. Is that not the case? Or are we doing something weird?

Thanks in advance
