I found a workaround that works ok. Made a macro that alt-tabs out, does the clicking for loading the latest autosave, then alt-tabs back to civ. Bound a keyboard shortcut to the macro and run it at the beginning of each turn.I too have the problem where it doesn't auto-update. Wish it did, would make life a lot easier. (I am playing on a version through GOG).
Would still want it to work like it used to tho.
