It's a OCC game…
Pretty hard for me to start at the wrong city.
Seriously, if I changed rules.txt to a 9 move Exp he'd go the yellow route. If I started a 1 move Exp anywhere on that route, goto Delhi would follow that route. I tried clearing the area around Delhi of blackness; no effect.
I have now tried making Exps off the yellow route by 3 tiles and their first turn is to go to the nearest point on the yellow route unless Delhi was closer than 3 tiles. See me-rt1.sav.
me-rt1a.sav is where I was blocked and decided to go back. The hills tile north of Rome needs a road to complete the link. At that time the Exps still take the yellow route. Then I decided to swing around the lake and try from the Delhi side while thet caravan did some blocking.
By the time I got up there I decided to test the route again before I wasted more time. That was sometime after 100 AD. This time the Exps took the green route. I loaded my 100 AD save and it was still yellow route. 200 AD was the next save (me-rt2.sav).
You should see some of the imaginative routes taken to other cities. I can only think that so much mountain and water messes with it, somehow. See also Campo challenge where I posted a similar change in routes.

Maybe the moderators have it in for you...
Well, I don't have much of a report to give since I lost the motivation to reconstruct the log after accidentally overwriting it. I was stuck at size 3 for a long time because I didn't have a Harbor (Seafaring passed over for critical path tech); afterwards I could use Rep happy growth to get to 6. It took Engr transformation and Ref to get to 11 in the mid-19th century.
AI beat me to Shake's and UN. Only the Germans were lower on the totem pole, and I only got tribute from them a couple times. I was so hard up for cash, without access to the seas to make trade easy, that using freight to build Hoover Dam was more cost effective than building Hydro and paying 4g per turn upkeep.
I hadn't time to build City Walls, so I lost population when subjected to bombing from the Germans and Egyptians after I launched. I barely hung on, landing in 2020. I can't imagine how Size 4 OCC is possible, much less Size 1 OCC.
