How to keep current level in map when I open a new level?

I mean do not unload current level when i load new level from BluePrint. (without streaming)

Open Level will unload the current level. So this is not what he searches for i guess.

looking forward an answer to this, would be very helpful

Really all you need to do is not call UnloadStreamLevel when loading another level.

Does the editor choke on the levels while playing or even when not?
