Hey Everyone!
I have a blueprint of a building which i have scattered around a map of mine, and within the building there are other blueprint actors which i have added to the blueprint as child actors. Although when they are added in the blueprint it lags my game 
In editor mode it’s fine but when I play the game (in PIE as well as all other options) the FPS drops from 120 to 20-40FPS
If anyone has any solutions to the problem that would be great!
Thanks,
Harry
EDIT: I am running on an Nvidia GTX 1070, Core i5 so hardware is not the issue
