Hey,
when I try to open a level in blueprints instead of opening it , it quickly switches between the levels and I did not see any one else got this problem
I recorded what happened
You’re doing something in your code that’s making the level load alternately 
Right. But in that level, do you open the other level in the level BP?
There is code somewhere opening both levels.
Try changing the name of one of the levels…
It is a problem in all of the levels in the project.
It always happen to me when I try to switch between levels in the project.
If you want to PM a link so I can download the project, I’ll take a look. Apart from that, I have no ideas…
