no-start-ma on delta import clears delta file

[IAmStevenJohnson]

We often get "no-start-ma" errors on delta imports and when we do, it clears the delta file so a full import must be run to get the recent export changes. Is it intentional, and necessary, that the delta file is cleared on this error? Or would it be possible to change this so when this error occurs, it doesn't clear the delta file so another delta import can be attempted? That's assuming this error is a glitch and retrying might help. I guess if it's definitely not a glitch and this error means a full import is necessary, a change of this nature wouldn't help.

@IAmStevenJohnson the delta should only be getting cleared after a full import. What's the cause of the no-start-ma error you are getting?
