Transpose master swaps out the active model for an initial version (old skinned zsphere version) of the model when switching back using TPose to SubT. There are some intersecting subtools but no more than I normally have. Subtools have been renamed without symbols and zbrush closed and opened after the edits.
Any ideas welcome.
Thanks in advance.
Yes, see the suggestion at the bottom of this page:

Jeez, thanks Marcus!
You are faster than a speeding bullet as usual 
Worked on the third try with symmetry.
For anyone else, exporting the subtools separately and opening them in a fresh scene worked. Using Transpose master in the new scene resulted in a perfect pose that could be transformed back to separate tools. This one is solved.
Thanks a million!

Kanga,
I’m glad to help. But you shouldn’t need to export the subtools separately. Simply save the model as a ZTL (Tool>Save As) and all your subtools will be saved together. You can then load the ZTL into a new project (Tool>Load Tool).
Ha you are 100% correct. Thanks, I was used to saving the tools out separately.
