Reply to AARGH !!! What is causing my timecode to flip out !?

So I have been having timecode issues since the last days of 2012.

First I bought new needles. (Got Shure M44-7s now)
Got 1210 recalibration, cleaning, tone arm tightening, new cables, new RCAs.
I clean my timecode vinyl with a piece of cloth before each set, and today I even cleaned my Shures with those little brushes that come with ortofons. I have dust covers for my technics.
I did a full tonearm calibration (height, weight and anti-skate) not too long ago and I do it about once a month, just to be safe.
These issues also appear when using my older Ortofon Concorde pros.
Also changing mixer channels (Scratch-certified Korg Zero 4) seems to have no effect.

I was 40 mins into a deep house set, not even halfway by far and traktor is freaking out, have a listen to the last 5 minutes or so:

What the hell is going on and how do I prevent it from happening again?
I sick and tired of this fucking up my mixes.
