CC keeps crashing when merging two polylines

[arc1112]

Hi,
I was trying to draw polyline along the whole section partially then merge them together.
But everytime I tried to merge two polyline CC crashed.
In addition, is there anyway to draw polylines completely manually not related to the cloud?

Thanks

What version are you using?

In fact, merging two polylines is not supported and the merge tool is properly deactivated now if you select multiple polylines. In previous versions it was possible to call the tool and it made CC crash ;)
