Reply to TP2.5 when syncing. As time continues, Traktor auto pushes the tempo up.

This is all well and good if im playing end of evening and the crowd are having it. Not so good if im playing early.

Traktor will push the tempo up as much as 2/3bpm in a 45 mins period. Ive not heard of this before and cant find any settings to diable. Im not illiterate when it comes to Traktor, but this is baffling me.
