When deleting an actor for the first time in level instance the editor hangs

When our designers delete an actor for the first time from the level instance it causes a hang that says “Computing References.” Sometimes this also causes the editor to crash. These level streams are part of two world partitioned maps and one of them has a data layer. After deleting the first actor, deleting more actors does not cause this hang and is fine for the rest of the editor lifetime.

Note I had talked to an other dev in the industry and they made it sound like this is just normal but to use feels like a bug. Would love some suggestions on how we might have setup our world partitions wrong.

Editor version: 5.4.1
