One for Celcat technies please!

Last week we did a three way swap of rooms.  Instead of changing the room resource on each event, we just renamed the rooms according to where the timetable should be eg A renamed as B, B renamed as C and C renamed as A.  When we as using the Client all the changes have been made.  However the changes have not been reflected in the timetables published with Web Publisher.

For example, a group was previously timetabled in Room A (electronics lab) all week.  The lab equipment was moved to Room B so we renamed Room A record as Room B.  Client shows the group are now in Room B all week, but publisher still showing Room A all week.  Changes were made in Client on 26 August and the date showing at the bottom of web timetables is 28 August.  Is there something we need to change in the Publisher settings?

Thanks
