CoronaLightMat behind refractive glass turns black

[Muadib]

i´ve just updated and having bit of trouble with the scene im working on:

my main light source is a mesh placed inside of a glass shell, sort of like a neon light.
if i use the proper light material and refractive glass, the light objects within turns black.

regular material with light emission works but that case i cannot get enough light for the surrounding.

am i doing something wrong here?

i tried to reproduce this and it only occurs when the environment map is on, either hrd or corona sky.

thanks ondra,

well, it seems odd:
i just copied the objects and the copy works. weirder still, the light is still being reflected even on the black version.

ive attached the scene and the rendering

old report, probably fixed already
