Help with low land value

[SoulStealer 12]

I have a bug in one of my city, a faulty lot caused school bus funding to go down to 0.
The lot is BSC Swi21 UniversityOfAthens btw.
Well I didn't notice it for quite a while during that time land value dropped dramatically needless to say High wealth demand had dropped too its at -6000 all the time. I removed the lot and bus funding was fixed. but no matter what I do RC$$$ is at rock bottom. I even tried ploping tons of parks, space port, marinas u name it. but demand is still at bottom. All other parameters are at peek level (environment, education, Health, safety, mayor rating etc) and also RC$ and $$ are high.
It's a big 600K city and I would hate having to obliterate it and start all over :S

Edit:
I used super demand mod to fix the demand and it seems fine now, I removed the mod and demand stayed within normal parameters, but no matter what I do land value is red all over (from edge to edge completly red!). even in the middle of parks even in the middle of my country club. When I plop some landmark or park pr trees it goes green for a while then turns red?!? surely it is a bug that infested my city without the super demand mod only $$-$ move into my city. any way to fix this using iLive or a lot or any other way?

 

Thanks

I am afraid you have found an unpleasant truth with respect to untested plugins. You should test each new plugin in a sandbox region (one at a time) before you put things in your precious cities.

Some of the stuff from here is mutually exclusive, but there are millions of combinations so the only way to find out is by testing.

You could try moving all your plugins out to another folder then running the game. If the problem goes away, then it is one or more of your plugins. If so, start moving them in, one at a time until the problem happens again, then remove the last plugin added, permanently.

Perhaps another reader can help you in more detail.
