In general, I don't know what caused it, but I was playing on a mirrored diamond map. At the end of my turn, I moved to an observatory on the territory of the orange player. After passing the turn, it started. The AI entered a teleport and started doing something – going back and forth, without leaving the teleport – and it lasted for a very long time (I figured it would be infinite, that the AI was stuck in a loop), until we decided to exit the game and reload from the opponent's turn, and I didn't enter the observatory. It seemed to work, but there was still a delay after passing the turn, specifically during the orange player's turn, but it wasn't long. Well, and it seems that I can't do without the observatory anyway, so I opened it, and the AI repeated its trick. In general, I started waiting. I did wait. But something is wrong here. And when viewing the turn, there's also some kind of glitch, a long delay – it feels like the game is about to crash. Then everything is normal, but the opponent's turn is still not visible.
