Crash when adding an skp object to an existing acene

I have existing scene created in sketchup 2015. I exported it to Fluidray and applied changes and saved it as a fluidray file. I open that file in Fluidray then when I added a a new object in the graph viewer, the node appeared then when i linked the new object node to the scene node it worked but the model did not show in the render viewer and fluidray crashed two second after

Thanks for reporting the bug. What version of FluidRay RT are you using?

I am using Fluidray 1.2. I have sorted the problem by opening the file, Instantly re save the file in a different name. close fluidray open the new file then repeat the process and it is fine.

Thank you for the response
