Brushes disappearing

Hello,

While using UE4.4 this afternoon, all the brushes i did today started to disappear on my map when i put them together.
(i was trying to make a basic column).
They’re all box brushes that i edited by moving their vertex.

The brushes are still there but not rendered anymore and all collisions on them disappeared too.

I tried to rebuild the geometry or restart UE4 but it’s still the same.

Help :frowning:

Those normals look flipped.

IMO, don’t waste your time with those brushes, just use something like Blender for your simple shapes.
