I upgraded 7.4 to 7.4.1 no problems apart from the Global moderator being changed back to moderator and name colour change back from blue to green.

The other thing was that I had to clear the cache to get the global moderator back to blue for the Top Posters island.

Still having problems with the Featured member Island causing a lock up of both Recent Topics & Topic replies if the days are changed from '0' to 120 days.
