Update of BO attribute in process not running rules on BO

I have a process called 'nam_initials_rebuild' that runs a rule which will rebuild the name initials field as

FIND Names WHERE Names.Type='Person' IN BATCHES OF 1
Names.Initials=SUBSTRING(Names.FirstName,0,1)+' '+SUBSTRING(Names.SecondNames,0,1)

It runs fine except the 'WAS CHANGED' rules on the BO don't run.

Should they or do I replicate them all in the process?

They should run unless there's a bug. You shouldn't replicate them in the process.

Is this something that will be fixed or do you want a bsv to replicate it.

A BSV would be nice

BSV sent with instructions

This has been fixed in build 1280
