Database Roles being modified by unknown process

I have two databases on two separate servers, with Merge replication running
between them. DB1 and DB2 both have the same 3 roles I created for user
access. Twice within the last week, the roles on DB2, the subscriber, have
changed removing most of their table permissions, but not all. Does anyone
know of something that could be causing this?
Thanks
Profiler is your friend - yo can trace Grant, Revoke and Deny commands like
all other commands and procedures. Check the "Security Audit Event Classes"
topic in Books OnLine.
