Different results in direct hdri reflections between last VRay versions

[gagui]

Here you can see the diferent results with the same exact scene rendered in VRay 4.1.1 nightly and the moth rencent 4.1.2 version.
What it is weird here is that the good one (antialiased and well sampled) is the older nightly version.

The thing is that I need to render this on the cloud and there it renders like the bad one because it using the last official VRay version.
What can I do?
Is this a bug or I'm doing something wrong?

I've just tryed the last nightly build and it renders fine so I suppose there is a bug in the last official release...
