Reducing the size of UVW causes the displacement map to not adapt to the new UVW scale.
Any ideas?
Hi it seems to me that the displacement map is actually changing but there is another map that does not fit with the displacement after UV scaling
You have the material tiling set to lower than one but the uvw mapping driving the displacement is set to 1 
What a day I’ve had, better to have stayed in bed today XD
Thanks fixeighted !!
Max has weirdly crashed on me multiple times this morning…all sorts of craziness going on, so I know how you feel
