When loading a Soft Object and directly placing the loaded Object into a Blackboard, after about 2 minutes the Object will unload and become null inside the Blackboard. This issue only occurs in a packaged game or when running the game in standalone.
Attached is a repro project with the listed steps setup.
This was reported and tested in 4.24.3 (CL-11590370). This was reproduced in 4.23.1 (CL-9631420), 4.25 Preview 2 (CL-12055273), and Main 4.26 (CL-12063615)
Results: After 2 - 5 minutes have passed the Soft Object will be unloaded
Expected: The object should not unload since it's being stored in the blackboard. Expected to have the same behavior as when you store the loaded object to a variable.
