UVWRandomizer: Different results from different nodes

[stehrani3d]

We have ran into this issue on two consecutive projects now. UVWRandomizer/Stochastic Tiling is producing different results depending on which machine is rendering the frame. Attached are a couple of renders from different machines, the road material is using stochastic tiling (please ignore the different glare settings). This is in CPU mode. The behavior is not consistent and re-rendering bad frames eventually seems to fix things. Some shots seem to render without issues, and other shots will have the same model and material wigging out.
Has anyone else come across this problem?

Thank you.
