Openfire 4.1.1 User can't see anyone but their group

Hi everyone, ever since we upgraded to Openfire 4.1.1 we have a very obnoxious issue, once in a while (Pretty much daily at this point) a user will report to us that they can’t see anyone that isn’t in their group on spark, we have found a solution which is clearing the: Group, Group Metadata Cache, Roster and User cache. However as this happens pretty much daily we want to get it fixed.

I would appreciate if we could get any help with this, maybe there is a version that has fixed this issue already.

Please try replicating with a current Openfire release, 4.1.5
