Hello one in all, on my most recent playthrough I have hit an odd variant of the turn ending bug where if a shared project should finish next turn the game will get stuck on the turn transition. This is on turn 323 and affects both the attempts to build Machu Piccu or a holy site. This is long after a great number of other wonders have already been built btw. Additionally if I were to try and quicksave and then quickload the save it does force the turn to transition however The shared project will disappear and the tile will still be considered to have construction ongoing on it.
