I'm not convinced what I'm seeing is the same as the projection problem 
we saw ages back in osma is it?
Have a look the spot where I first noticed what I'm seeing.

At z12 Kaikoura is where I expect it, if you zoom out one lvl to z11 you 
can see the big offset. If you zoom out to z10 the offset stays about 
the same.

Why is there such a big jump in offset from z12 to z11?

This is the screen shot I previously mentioned that I took around the 
15th August when I could see two captions.

The name that is offset is from a freshly generated caption layer, the 
correctly placed name is from a previously generated lowzoom. Why would 
the name be correctly placed before the 15th and offset after it?

I was generating caption layer for z6-11 for New Zealand around the 15th 
Aug and it seemed to me that everything went from not being offset to 
being a few miles south at that point.
That's what made me wonder if it was a client problem in or/p that was 
introduced about the time the proximity filter was added  which was the 
6th Aug.
