UE5.4 World Partition doesn't load when load from save game

Hi,

I am making on a semi open world game utilizing world partition. since the world is quite large, I set the WP loading range on world settings to only 100UU. Since I can’t access the loading range directly, I override it using the WP streaming source that I put on my character, and using timeline, I increase the range until the target range. (Need to do this to avoid Out of Memory because of loading peak memory usage)

It’s all normal when I play the game from start (New Game), however It’s not the case when I load the game from save. Somehow, the world partition system itself is broken. It only loads the persistent level, even though there is atleast one streaming source in the level.

I believe that the WP system is broken because normally when debugging the world partition using “wp.runtime.ToggleDrawRuntimeHash2D” it shows the debug of runtime hash in 2D. However, when I tried to use the debug on game loaded from save, the game crashes with this error: “page fault (user read data, page not present)”. I tried to reproduce it on the editor, but it’s normal. Somehow the bug only occurs on packaged build.

Note: I already icnlude all the maps in the project settings, and it’s working normally when start from new game. So, the content not being cooked is not the case

Any update on this topics? I also planned to develop an open world game and use WP system
