Bug / Crash Fluid Renderer doesn't work on two sample scenes

[redhairjino]

I've reinstalled Unity and updated Nvidia graphics drivers to make sure every other things are all up to date.
Unity version is now 2018.2.4f1.

I've created new project in Unity, then imported Obi Fluid 3 to the project.
Then went straight to Obi>Sample Scenes and opened all 11 sample scenes.
All sample scenes work properly when I pressed Play except MultiphaseFluidBuoyancy and SimpleFluid.
Both doesn't show fluid on Game window when played. 
It shows particles when I check 'Render' check box on Obi Particle Renderer, but doesn't render fluids when I uncheck it.
It seems like Obi (Simple, too) Fluid Renderer doesn't function properly, but I can't see anything wrong with the settings.

If you want screenshots or anything else, please let me know and I will gladly post it here.

Thanks.

The sample scenes still do not work, but I've made new test scene working replicating components and values from sample ones.
I don't know what changed, but I am glad it worked.
