Add a proper error message when project is ON HOLD and it's impossible to change statuses of tasks

Hi, during investigation of this thicket https://support.workfront.com/hc/en-us/requests/1144562?page=1 I noticed that when a project is ON HOLD I'm able to change statuses of tasks but the system is not able to do that (when, for e.g. I'm trying to move one task under another). According to the ticket, that's intended because the system shouldn't do any changes in projects. I'm getting this error:

"Unable to complete operation for a project of status Backlog"

which is meaningless. Could it be replaced with a proper message, like

"Your project is on hold and it cannot be modified by us, only you are allowed to do any changes" or something else.

Giving a proper error message would be very helpful. I see that even your support team didn't know what it means.
