I created a simple Data Asset with a few vars.  
This Data Asset is used in a function as a parameter and an array.  
It works fine actually if I try to use it, but once I restart the engine all uses of the DA change to “Object references” which breaks the whole Blueprint: Variables of the Data asset and Arrays of the Data Asset are suddenly objects and all node connections too, which then in turn cause errors obviously.

Here a simple function for example - before and after an engine restart:

Hey zale90,

I’ve tested this in a clean project using a Blueprintable Data Asset C++ class as my variable type, and I’m not seeing the same results. When I restart the project, my data asset variables are not being reset to Object References.

Could you reproduce this issue in a clean project and provide me with a detailed list of repro steps I can use to see the issue on my end?

Thanks

Sorry for the late reply, have been really busy.

I created a clean project with the same Data Asset and a pretty much equal Blueprint with not problems after a restart.

I “fixed” it in my other project by loading the project’s module earlier: Changed LoadingPhase from “Default” to “PostConfigInit” but this causes problems with other plugins.
