Hi appointment-insect,
I have asked for the file, no reply so far.
We had a meeting this morning, and I had placed my question last night, but as you can guess, with the tech support's reply: no workaround, like telling use this setting, or this parameter needs to be 2X.
If you send anything to a render farm, make sure they have the exact same version running!
So sorry to make you wait.
Fingers crossed, it will be addressed in no time.
Cheers
