I cannot provide additional information, only summarize what I know of this case.
- World: zz5
- City ID: 17840 (most likely - city name has been changed, but the city was conquered that day)
- It was a ghost town at that time
- Democracy was researched (thinking of it, it´s weird in itself that democracy should have affected the conquest time in a ghost town. If I remember right, democracy should not affect ghost towns, and this research does not even exist on hyperborea worlds.)
- However, we still have this strange issue with the actual server time lagging one hour behind, and the issue described above seems to have occurred around midnight. I don´t know whether this could cause such strange effects.
Maybe the logfiles can help solve the riddle. I must admit that I´m curious by now...^^
