Trying to price some different variations of a RTW, and thought the online tool might help play with some options.
Frustratingly it is showing NRT-YVR as unavailable on all days, even when there is plenty of JL D inventory both on ExpertFlyer and through AA RTW desk.

The itinerary is OSL-LHR-xDOH-BNE-NRT-YVR-SEA-LHR-OSL. It seems to be just NRT-YVT that is problematic.

Any thoughts on how I get past this error? (Other than give AA all my different variations and wait 24 hours for them to price).

I'm using the "old" tool. The "new" tool won't allow me a second stop in LHR: "Your trip may not include two stops in London without visiting any other city in Europe-Middle East. I am dropping one of the visits to London" (another bug as this is permitted in the rules).
