See this UFO here?
This is a prop that we placed down, not knowing it had no collision. And yes, we tried restoring from backup, but Zynosc accidentally pressed 'Create New Backup' instead. Yikes.
Epic Games HAS fixed the collision bug now, but NOT for ones already placed in maps.
Until that gets fixed, and we can delete the UFO, this will be staying in the sky.
Hopefully it is fixed soon, and Epic notices their mistake, because the UFO was supposed to be gone in March. It's May.
