on Mac desktop, game has worked fine for months and much fun but have hit a wall, first started to crash to desktop during play when hitting the top right button which displays holdings, vassals and succession. Now, it crashes when loading any saved games after a certain point (about year 1299), crashes right before map comes up. I can start a new game or load older saves but if load an older saved game, play to a certain point and save, then that new save will crash in same way (same prob with autosaves). any ideas?
