High Wealth Residential (R$$$) demand glitch

Hello,

I've encountered an odd problem in my region; namely, all of my cities have (seemingly) infinitely negative high-wealth residential demand. The nature of this demand is so highly negative that it overrides even the super demand ordinance; if you activate it, all your demand skyrockets but R$$$ remains stubbornly at -6000 (or below).

To address this, I removed my first suspect, the large custom airport, from the region by moving the respective city tile out of the folder.

Doing this (then running another city to check demand) caused the restoration of normal R$$$ demand.

So, I decided that some lot in one of the airport packs must be causing the issue, so I systematically deleted each type of lot on the airport.
Even after the airport (and all other buildings on the city tile!) were demolished in this fashion, the region still had the demand issue.

So all in all, I'm at a bit of a loss. I've never encountered a situation like this before. Any ideas?

A low R$$$ demand is seldom a glitch, since less than 10% of all your cities' employees are rich people.
If the base demand is way below zero, no super demand mod will ever be able to turn it into positive figures.

Any further analysis would require a screenshot of the Census Repository Facility's query.

Here's a repository shot. The R$$$ demand (regardless of what I do) always sits right around -6000.

Well, I can see that you don't have enough schools, as your EQ is only 27. You'll need to educate your population a bit, which will boost the payscale for the types of jobs the workers are seeking, which should ultimately bring in R$$$.

Is the projected R$$$ demand really negative, -6,290 ? ()what()
If it is, is it the same in all your neighbouring cities as well?

JamesSanner

Correct, the projected demand is that low in this city and every one in the region.

RippleJet

I didn't even know that could be negative... never seen that before... &mmm
I wonder how you've managed to reach this situation... ???

That projected demand is the sum of all actual capacities plus extrapolated demand of all your cities in your region.
Upon starting a new city, the R$$$ capacity is of course 0, and as far as I known, the only way to extrapolate negative demand would be by actually allowing too much R$$$ to grow in the city (more than the actual demand).
The sum of what's grown and what's extrapolated should always be larger than zero though...

Would that projected demand still be negative if you start a new city in your region?

JamesSanner

Yep, tried that too.

The only thing that seems to change it is removing the city containing the airport from the region folder. When I do that, the demand goes to a more normal value.

Can you provide a link to which airport pack it is that you think is the problem? I'll take a look.

Sorry it took so long for me to reply:

I use basically every airport pack available (with the exception of the older ones). All the RMIP packs (RMIPv1, RMIPs2Vol1-4), the Aerospace Consortium (AC Team)'s lotted jets/jetways series 1 Part  1-2, SWAP pack 2.3, Trainguy4449's "runway with large jets", 4ms airport billboards.

The strange business is that I've built airports before in other cities with absolutely no problem.

EDIT 5/5/2010:

I went into the city in question and began destroying lots one by one to see if I could alleviate the problem. Every tile in the city was eventually cleared, but the glitch still existed. So, I used the "Obliterate City" option, which corrected the demand glitch.

i am having the same problem too. has anyone identified which piece is causing the glitch?

RippleJet

I don't think so...
I've personally had a similar experience of the mayor rating being massively negative, regardless of what I did.
It might be that something got screwed up during a save operation.
I also couldn't find any other solution to that problem than obliterating the city. :(

You know it's a problem with that particular city, so it's either a lot (which you should be able to fix) or the game save itself (which you can't).  Before taking such drastic action as blinking your sims (and your hard work) out of existance, I'd try to isolate your lots using a binary search, in case it's a lot.

Make a backup of your city first.
Now check if it is a building or lot in the first place, or the game save itself.  Bulldoze EVERY TILE on the entire map.  Use the bulldoze tool - you want to make sure you get every last tile from corner to corner.  Rebuild the repository only.  Let it run for 6 months.  If the problem is still there then you're screwed, sorry.  Scrap the city.

If the problem is gone with everything removed, that's good news.  Continue...

Bulldoze half of the city, right down the middle.  Let it run for a 6 months and see if anything changes.
If the problem is gone, this half is not the problem.  Reload the city and bulldoze the other half.
Save.

With 1/2 a city left, bulldoze half of that so you only have 1/4 left.  Let it run.
Problem gone? --> Reload the 1/2 city, and bulldoze the other half of it, leaving the other 1/4 city.
Save.

Keep chopping the city in half.  It should take about 5 to 8 chops.  Always make sure the problem IS still there, until you have just 1 building left (and your repository to check).  If you delete that last building and let it run, your problem should be gone.  If it is gone, you've identified the culprit.  Reload the backup.  Remove all instances of that lot.  Let it run for 6 months and check again.

If the problem persists, then either you missed an instance of the lot, or there's another lot with the same bug.  Make a backup of the current save with the first bad lots removed, and start the binary search again from the beginning.

Don't forget to report back if you find any glitched lots.  ;)  GL!
