The unit and buidling queue seem not to work anymore. The farming feature and starting cultural events still work as usual. Do you need the logfile or debug.txt for checking?
[Edit]
Just checked the debug.txt, there are a lot of these "Ingame error in attackFarmers2Response(): Ungültiger Zeitwert ( 10800)" errors

Without having changed anything, the unit queue is working again. Building queue not yet checked, but I assume it does work too.
