Very strange garbage glitch

[delta9]

Last night I was working on expanding my new downtown and was stuck wondering why there was no CO$$$ development, much less any at all in my new commercial zones, considering the high demand.  I poked around the data views and took a look at my land value, and saw splotches of red everywhere in areas that should have been astronomical (SC3000 flashback anyone?).  I flipped through some of the other data views to find any correlating factors, but there was no crime, etc... but in my tired state I forgot to check the garbage view.  So I shrugged and left it running overnight as I am wont to do, just to see what would happen by morning (hopefully not another industrial fire ).  When I resumed I saw no new development and even some abandonment... "due to low desirability."  After a "what the hell?" the news ticker informed me of the citizens' displeasure with the garbage problem.  "Garbage problem?" I thought.

Almost 100,000 tons.  Oops.

Apparently my Nexis WTE plant had died an unnoticed death a little while back.  So I plopped down that freaking gigantic CSX WTE plant.  Seriously, that thing is huge.  "Problem solved." Right?

No.  For some reason, the garbage level refuses to go below about 33,000, in fact it approaches it asymptotically.  Apparently my 0-level was reset to 33,000 on the graph, but on the garbage and land value data views everything looks pristine, and I can manage to get those high wealth offices to grow where they previously wouldn't, so I'm not worried about 33,000 tons of mysterious invisible garbage laying around like I was before (now I can save ).  I thought it might be some kind of glitch having to do with the CSX plant eating up all the garbage nearly instantly, so I tried it the old-fashioned, slow way, with a landfill.  Same deal.  Even after 20 years of being at that point, it's still a flat line.

So that's my long winded story about something that's really inconsequential in the end.

What gives?  Anyone ever heard of this bug or run into it?
