I can now confirm that this is a 100% reproducible bug, and a pretty severe one 
at that.  You should be able to reproduce this issue at will if you follow 
these steps.  It may actually be possible with less servers and less steps, but 
here is what I did in a test lab today:

1. Create a brand new FreeIPA domain in CentOS 7.2 / FreeIPA 4.2.0 with 3 
servers, dc1, dc2, dc3, replicating any way you want.
3. Use ipa-replica-manage del dc2.ipatestdomain.net, and then delete the server 
/ vm / whatever you have it running on
3. Install Fedora 23 on the same IP address and hostname 
(dc2.ipatestdomain.net).  Install FreeIPA server 4.2.3 from replica file 
created on CA master (dc1).

Check aci on dc2.  You will notice it's now missing a bunch of stuff.  So 
basically, all it takes to lose that ACL is to create a Fedora FreeIPA server 
and join it to a CentOS domain.
After I had upgraded all 3 to Fedora, that ACLS was lost permanently as it no 
longer existed on any server because there were no CentOS servers left.

I'm assuming since this is so easy to reproduce, that you don't actually need 
my log files.

ACL comparisons below for reference :
1. ACL on dc1 when its on FreeIPA 4.2.0 on CentOS 7.2 and the domain consists 
of only CentOS servers
2. ACL on dc1 when its still on FreeIPA 4.2.0 on CentOS 7.2 but there is now a 
Fedora 23 FreeIPA 4.2.3 server in the domain (for reference that the CentOS ACL 
hasn't changed yet)
3. ACL on dc2 when it's now a Fedora 23 FreeIPA 4.2.3 server created from a 
replica file made from dc1, the centOS 7.2 CA master(missing some stuff)
4. ACL on dc1 when it's now a Fedora 23 FreeIPA 4.2.3 server (now missing some 
stuff)
