Instancing error

Hi all,
I was trying to make a grass scene and I get this error:
ERROR: Singular matrix in MatrixInvert: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1
I have managed to reproduce it on a sample scene, lowing the number of instances solves it, but I get grass holes.
Best regards

Here's an updated BlendLuxCore from current master.

(this is Windows 64bit with OpenCL. I can also offer Linux without OpenCL, otherwise you'll have to wait until the next alpha release to have the bugfix).

Hi,
Have tested it and now I get a crash when stopping any render. No error on windows console.

Maybe my build has issues or it's a recently introduced bug.
It's probably best if you revert to the last alpha release for now.
Does it happen with every engine (CPU/OpenCL)?
