Hoping to get some assistance (again) from the experts. I am in the process of planning 2027 travel and the routing I am coming up with looks like it could be worked into a DONE4. Before I spend a lot of time planning it all out, I want to confirm that it would work with the non-negotiable destinations. I played around with the One World itinerary builder and got some error messages. I know it has it's issues, but wanted to get your input and suggestions. I have done two of these tickets before, so I am not a total rookie, but I don't have the experience that many of you do! Here is what I put in the builder:

OSL xLON-NBO-DOH-MLE-KUL-HKG-LAX-HEL-OSL

I get this error message under the OSL-LON & the NBO-DOH segments: Your trip may include two stopovers over 24 hours in the continent where your journey started. If your itinerary includes both of these in your country of origin, one must be outbound and the other inbound. Additional stopovers under 24 hours are permitted in your itinerary. Please select a different date or flight.

The destinations that need to stay are NBO and then back to Europe at the end. I will add more segments once I figure out if this is even doable. The MLE stop is not a must if that throws anything off. I could go straight to Asia and get my beach fix in the Philippines. Other than Nairobi and ending in Europe, I am open to destinations to add in.

Thank you in advance for your help!
