Mesh LODs all screwed up after update to 4.18

The “screen size” settings of all my meshes LODs are way too high after the engine update, so I have only very low poly meshes all over the map and would need to fix them all manually.
Am I doing anything wrong?

Sometimes updating projects to newer versions of the engine breaks things. It’s not the first time LODs have broken.

It’s normally suggested to stay on the same version of the editor for an entire project. Or at least only update when absolutely necessary.

Just reaplying lod settings will fix this. Better to write some c++ script to fix all your lod settings.
