TwoNodeLink: invalid orientation vector error

[SaeedT]

Hello Everyone,
I have an 'ElasticPP' element assigned to two nodes that makes it perfectly vertical in the Z direction(X and Y coordinates the same but different Z values). I get "invalid orientation vector". There is another similar element that is not perfectly vertical and I don't get this error for it. If it was just a warning, I could ignore it but it kicks out the execution. The model is too big to post here. I may move nodes a bit to go around it but I thought this should be reported.

Thanks,
SaeedT
