Toggle stream level visibility crash

Hi! I dont know why but since I started to use streaming levels and volume nested udner persistent level Ive been having serious issues with like…Everything…

It works mostly now, but when I try to toggle the visibility of the streaming levels the engine crashes entirely with a Assertion failed: Level → bIsVisible == shouldBeVisible Kernel 32.dll error message.

Someway along all of this I renamed some maps and moved them, and clicked fix redirectors. But soemthing with my references or memory must be totally messed up, since sometimes when I click “fix redirectors” it just says “failed to load assets”.

I dont know why but renaming assets has always been the hardest thing for me like ever in UE4.

Ill post the entire error message below.

Please help:(
