mmaxe01, when you say that time isn't passing properly, are you referring to the game's timers or villager productivity? There's a big difference, and the underlying issues are not always the same. If it's a system clock issue, villagers may not age, nursing moms' timers don't change, fruit trees will have problems, etc.

If it's a productivity issue (and that's what this is looking like), it could be a _bug_ related to the game's real-time engine, as long as the things I mentioned before are working properly. However, we would need more information in order to determine if that's the case.

Are you only having problems with building projects and research? Although it's unlikely that this would apply to all of your builders and scientists, I need to ask if your builders and scientists have farming skill, as well. If so, and your food supply isn't at least 400 or so, they will leave their assigned tasks to harvest any available food (to help ensure the tribe's survival).

If that's not the case, then we need to have a look at the RTE in the game to make sure that it's doing what it's supposed to do.
