Clarification needed, to aid in troubleshooting this issue:
1. Is this game lag experienced only in OL, only in the "home world," or in both OL and the "home world"? Which world did it happen in, first?
This is not specific to any world. When you get the problem it happens in the homeworld and in all subhoods. It is not caused by routing errors, stuck sims or animals or any of the other things one typically associates with lag. It probably shouldn't be called lag at all because that is going to cause well intentioned simmers like you going down the wrong path trying to help. This is rightly a bug with the game clock. Active sims can no longer complete simple actions in a normal amount of game time. It can be so bad that the sim will seem to stand there forever doing something a simple as sitting in a chair which might take the sim an hour of sim clock time to complete. Think of The Sims 1. Slower than that. Much slower.
2. Have you checked for routing errors in the world? Stuck sims? Stuck animals in home world? Multiplying spawners? Abandoned cars/vehicles? Too many NPCs spawning at certain places in the world? Any other causes for lag noted in any of Crinrict's stickied threads? (It is important to eliminate all known causes for lag, before we can accurately pinpoint a new cause for lag never seen before ITF.)
It has nothing to do with routing errors or any other kinds of errors associated with a specific world because it happens the same way in all subhoods. The game clock is messed up.
3. Is this happening in factory reset games or is it only in pre-played saves from earlier expansions?
I am trying to reproduce that for myself now. I had to ditch all my pre-played games.
4. Are you playing with any EA cheats turned on?
5. Did you visit Utopia? Did you visit Dystopia?
No. University.
6. Is the same approximate amount of time needed for causing the corruption/lag similar in every game played, or does the amount of time needed to cause the corruption/lag directly relate to the number of time jumps? In other words, can you "cause" the problem by doing several consecutive time jumps, with only one day or night between jumps?
We don't know what is causing it. We are trying to figure that out. We only have theories.
7. Are you spending most of your play time in the "home world" or in OL?
Most of the play time was spent in University and some little amount in OL. I am sure that Cyron has a different answer.
8. Can you move the lagging save to a factory reset game, and still experience the lag? (This would eliminate lag caused by anything other than the save, itself.)
Yes. I did that. I had to abandon the game itself.
9. Please let us know your computer specs, which OS, and etc -- all the things Crinrict asks in her bug thread.
I promise this has nothing to do with sub-par specs. I have a Core i7 quad-core processor, 24GB of RAM and an HD 5850 graphics card, with over 300GB of free disk space. Brand new games in most worlds other than Isla Paradiso run fine and there is no lag. Again. I think lag is an extremely misleading term for this problem. The game clock is messed up.
