Demand Bug

[EdMan#1 1]

I need help with this problem. I have recently started a region. So far, I have several residental cities & one main city with commercial & high tech industry. To this point, demand for high tech in the residental cities (or any other city for that matter) is very high. I had started to build industrial for high tech in the commercial city. It grew to about 4,000 jobs total. Both I-D & I-M are taxed to maximum to avoid them to grow. No I-A. Then demand tanks in the commercial city, & it is now at zero (no positive or negative demand). I previously had the Industry Doubler mod available on the STEX. I thought that was the problem, so I removed it. I re-enter the game, the buildings now have the normal capacity of jobs. The demand went up again. I zone some more industrial, & it grows, but again the demand stagnates at about 4,000. I have one seaport in that city, & it isn't even close to capacity (~200/500), so I don't think it has to do with bad freight trips. The demand is still high in the residental cities (it is at 6,000 in the demand graph, maxedf out). Can anyone help? It would be greatly appreciated. Thanks.

(Note: Could I-H be dependent of I-M or I-D? I have enough I-D because there is no demand, but there is very high demand for I-M, but I haven't given ti any space. I don't thjink this is the problem either because the I-H demand is high in all the cities except for the commercial one. Could another factor be the large amount of commercial jobs in the city? Esp. CO$$$?)

My guess is that HT won't grow because of the pollution from the ID and IM. The only real solution other than an air cleaner is to bulldoze the ID and IM and wait a few years for the pollution to subside, or to zone HT in an area with low pollution.

You should know that IH is very reliant upon a high education.
