Bug in Deliver: Render path is not accessible to Resolve

This turned up in B8 when trying to add to the Render Queue, whereas I had no trouble in B6 and B7. It may be an issue that's been around for a while: viewtopic.php?f=3&t=19650 although possibly for other reasons.
The actual path IS accessible as the entire project lives in a subdirectory there, but even using the exact location in Media Storage can't convince it to add to the Render Queue.
