Update : After I reproduce it on a clean scene, the crash dose not happen.
So now, I guess some combinations of another things and Ornatrix in the complicated scene lead to the crash problem.

But, when I try to move OX hair roots, it move way too far.

I mean, I still can not move the roots where it needs to go.

Only I can do is just remove and re-plant the roots. That's little hassle though.

I'm using the lastest V5.2.9.14713 with 3ds Max 2017.

I sent the reproduced scene for the testing to Jeordanis.f@ephere.com.

Thank you for your time.

FYI :

In my scene, at some point, I can not remove roots any more.

When I try remove root, I got this error messaage. Very frustrating.

I don't have time to redo editing guides,

Thanks for your reply.

I sent the scene file for testing to Jeordanis.f@ephere.com again this morning.

It might be in your spam folder.

I'll try the latest nightly build, 5.2.9.14953, like you said.

Hopefully it works out. Thanks.

All right. I'll try the lastest nightly build. Thanks for your response.
