This crash was previously being tracked in [Link Removed] with a generic "Assertion failed: ModuleInfo.Module.IsUnique()" error message. Ben.M updated that with CL 3376654 and commented:
"This could come from a bunch of places, and isn't a bug with the module manager itself, but a bug in code that's using it. I've changed the asset to a fatal message that prints the module name, which can be used to create separate bugs for whichever modules are being referenced incorrectly."
Now in 4.16, all incoming crashes I have seen have the following error message: "Fatal error: [Link Removed] [Line: 567] Outstanding reference to module 'Renderer' while trying to unload it. Strong references to module interfaces should not be kept."
repro steps currently unknown
