We are aware of some inconsistencies in how NT4 responds to the vampire 
process. We have not invested the time and energy to fully understand what is 
going wrong. If you wish to debug this to help find the problem we welcome 
the input, however we can not spare the time to work on this at this time. 
Additionally, the priority for this feature is reducing with time so that 
makes it more important to focus on activities that enhance future value 
more.

I do not intend to sound dismissive or rude, this is just a resourcing 
problem.

Cheers,
John T.
