Adding Reverse Route causes 50% loss

[richard.dean]

I am building some IPSEC tunnels where thje remote locations have Dynamic IP addresses. It works fine, but I need to add more sites, right now I just have the one. When I add the reverse route statement, i start getting 50% packet loss based on ping responses "!.!.!.!.!.!.!.!" If I remove the RR it works fine. "!!!!!!!!!!"  Question is, what am I doing wrong or do I really need the reverse route? Right now the ACL is for the one subnet for current location, but I will be adding more sites. How would I adjust the ACL for more remote subnets if the remote sites are doing split tunneling and the ACLs must match?

I removed the reverse route, and also removed  "

match address 115" as neither is needed in this scenario

I think this will be what I am needing, but still curious as to why the RR appears to drop packets> I don;t need it now because I will not be advertising those routes, but still wondering.
