There seems to be a bug if an NDI DAT is placed inside of a COMP that is replicated. I came across this while working on a large project that creates multiple replicants.
The issue can be replicated easily by placing an NDI DAT inside of a Container COMP, then replicating that at least once.
Using build 2023.12370 on Windows - AMD CPU.
Not sure if it will help but I’ve attached the .dmp file.
