In the attached saved game, the unit yet to move is a military engineer. If you railroad the adjacent holy site, the game crashes two turns later, i.e. at the beginning of turn 274. (An autosave is generated, but I never get control, and don't get notified of a splendid commercial hub finishing.) While originally I did things on turn 273, you can simply shift-return to skip thru turn 273.
Moving the apostle there away doesn't help. Moving the relic inside doesn't help. Moving another apostle in Canada so it doesn't die to generate a relic doesn't help. But it does NOT crash if I do not rail that tile.

Also, for the diplomacy bug, my alliances recently ended, and they wouldn't accept Friends immediately after. However, from this save both Egypt and Hungary will offer Friendship, with the new option never to pester me again. HOWEVER, if I decline friendship for now, we become Friends anyways. I suspect this is due to the coding of the new option.
