LMA in Qunrir. Probably stuck with Leostryker. He will never stop. He doesn't discriminate- he attacks everyone and he is good at it. Even if you are shuffled out, you will likely get shuffled back to him at one point. A real-life friend had him in their hood for like 8 out of 10 weeks (because even when neighborhoods shuffle, some people from your old hood will be in your new hood.) RL friend was ranked nearly as high as Leo- he attacks everyone. You have to adapt or just deal with it until it is over.
And, while I'm sure this will make you even angrier, I'm going to give more unsolicited advice. Stop going through tech. You need to get all of your buildings up to LMA. You have BA goods buildings still- 4 eras behind you. Those are worthless to you. Slow down and focus on your city. Not tech. To put it in some perspective, last week I aged a city in Z-World out of Bronze Age with over 120K points. BRONZE- as in 4 full ages behind you yet only 10K ranking points below you. On a new world, too, so no fancy buildings- just a Zeus, Oracle, ToB, LoA, some blacksmiths, some houses and a Royal Cascade (from an event and only there because I couldn't take any more blacksmiths- my sanity would not allow it). No goods buildings. No military buildings.
