Error on template relinking after unlinking

[hundux]

I get this error after these steps.

Unlink (not unlink and clear) a web scenario template from a host
remove a scenario step from the scenario in the removed template
Add the template again to the same host
Click "Save"



ERROR: Cannot update host

Error disappeared after removing web scenarios from the host manually.

Seems to be just an non-intuitive message
