I looked at saves 141 through 144. It became clearer. The Dragon Utopia was only revealed on 144. Before that, the direction of movement indeed leaned toward the sandy treasure zone; after the Dragon Utopia was revealed, it really could have been changed... But, excuse my bluntness, I feel Britvochka's skill level is somewhat exaggerated. I am saying this based on reviewing the under-layers, not just one specific save.
And as for 145 specifically, I would take the Dragon Utopia with Craig and return everything to Gurni, and then head toward the pink player and into their treasure zone.

Have you seen the template scheme? You played well in that way, but what's next? Well, if nothing useful was given in the pink AI's treasure zones, does that mean you should surrender? Calculate the time when you will arrive in that territory. Even if Craig takes the utopia on 147, you'll still need to return the army through the swamp, and only Craig has pathfinder. On 211 you can reach the pink player, then go into the treasure zone, and the road could easily take three or four days, or even more, then another three or four days for clearing + it would be a good idea to hold the chain to the Castle so that Nela doesn't accidentally appear from underground. Even if everything works out, Nela will likely already be settled on 217 in your Castle, having combed through the center (and you almost certainly won't have time to do anything properly before then, as you'll be wasting time on the road). Wouldn't it be better then not to go to the pink player, but immediately after taking the utopia, break through ГО and devour the underground treasure?

P.S. 2Redmi: I have nothing to say to you. Aside from everything else, I don't see any particular "pro-ness" in finding the utopia; it's a standard online move.
