I've left a few comments inline. Additionally I'd like to ask if adding this logic to ErrorRaised but not to WarningRaised is intentional. Even if restore didn't produce any warnings, I feel like we should behave consistently between the two for future-proofing.

I was discussing this implementation with @rainersigwald, but probably I didn't get him right.
Let's wait for his input.

I agree with @ladipro: the same logic for errors should apply to warnings. We shouldn't ever fail to log a warning or error just because it happened at a time where we weren't fully expecting it.

Oh and please add a Verify test of a project that fails during Restore.
