Trying to submit a bug report and its not letting me post it.
Seems like adding and array of verse devices to another verse device causing unbearable load times before allowing and edits to be made to UEFN. Editor freezes up for almost 5 minutes before allowing you to add verse devices to the array. Then after it unfreezes and you actually select something in the array drop down or even with the eye dropper you have to wait almost 2-3 minutes before the editor will unfreeze again. We have 16 devices and 16 arrays per devices. This will take us easily over 7 hours to change all of these.
