There are some issues with Fortnite that prevent us from designing in live edit. These all happen while in live edit, not in UEFN. Here they are:
-Bouncy props will bounce the character even in phase mode. This makes flying inside levels to get to somewhere hard because the player would bounce randomly in an asset, then all controls don’t work anymore, and character phases through all geometry and fall under the level. This is very common when you have bouncy props in the map (like seating with large Umbrellas, or tires)
-When you mantle and switch to fly mode (double jump), you instead phase through all geometry and fall under the level instead of switching to flight mode.
-Having a day sequence device with a zone prevents any building inside, the zone is selected with the phone instead
