Bug description

This issue appears to be related to the previously reported #13687, which was partially addressed in #13694. However, this specific error seems to still trigger within nested Replicators with groups (not sure if really related). Apologies for the number of closely related issues, our setup makes heavy use of deeply nested replicators 😅

I’ve attached the relevant replicator / blueprint configuration to make the issue reproducible.

                          Bug description
                          This issue appears to be related to the previously reported #13687, which was partially addressed in #13694. However, this specific error seems to still trigger within nested Replicators with groups (not sure if really related). Apologies for the number of closely related issues, our setup makes heavy use of deeply nested replicators 😅
                          I’ve attached the relevant replicator / blueprint configuration to make the issue reproducible.
