IBL + Physical Sky (Sun) = No Caustics

Hey everyone,
There's this issue - when using IBL + Physical Sky (Sun), the caustics will not be produced. Is this a bug?
Sorry if this has already been posted (I have a slight feeling of deja vu) Maybe, I've just forgotten to post it earlier...

Is the IBL map used for illumination? Maybe it doesn't have a sharp enough lightsource to make sharp caustics.

OK, I've reset all the environment settings for the scene and it seem to be working fine now.
As for the the settings
- the environment was set to IBL
- Sky settings: Physical sky + sun enabled
- all the layers of 'IBL settings' where set 'HDR Image'
Now, with this settings, when I tried to switch 'Illumination' to 'Active sky', no caustics would be rendered.
I mean, one can clearly see that the Physical sky is now being used for illumination instead of HDRI, accept no caustics would appear.
I swear, I already had that sort of problem before, but for now, looks like some sort of minor hiccup, I guess...
