Hey there @hulebaji! Does this apply for all level BPs or only the pregenerated levels?

To test it, could you try creating this same type of new level,

Then select the open world variant, modify it’s level BP save all then let’s try that again.

If I may ask, what are your specs and is this 5.1?

Thanks for your generous help, my version was 5.0.3 before, but it’s still not working, I am installing 5.1 now, and I hope it’s going to be work

Not only level BP not work, and also the other type Bp such as actor BP, but it’s ok to place objects into level

All blueprints are failing to save, but level changes save correctly? That is quite odd!

In the console log when you press the save button in a BP, does it show this validation?

AssetCheck: New page: Asset Save: LightSwapper
LogContentValidation: Display: Validating /Script/Engine.Blueprint /Game/Work/AssetChanger/LightSwapper.LightSwapper

Try saving a blueprint, then go to it’s project folder and see if the uasset appears and stays. Then save and quit the engine and relaunch and see if the assets remain in their folders but aren’t seen in project. If that occurs, we’ll have to delete all the caches by hand.

save your map then close
