PrecomputedLighting Scenarios - Foliage BuiltData Not Saved

Hi, I have a peculiar problem. I set up lighting scenarios exactly according to the documentation but there seems to be a problem with one thing in specific and that is foliage actors.

They bake fine, don’t get me wrong, it’s just that even though I save everything (all levels) and then close and open the editor up again the lighting information for foliage is somehow twisted and corrupted. I am not sure if it’s entirely missing (seems to be on the grass but that can be because of the low lightmap res of 4).

I attach screenshots of the scene as it looks after it’s baked and then as it looks after it was closed and opened again.

Right after Bake

Opened from Saved

This is a big problem for me (scenarios basically unusable - most scenes have foliage of some sort) and I am not very sure how to resolve it as there seems to be no indication as to why this happens?

So I am trying to file a bug report and see if you find anything. I can attach the scene as well but since it’s 5-6GB I’d rather wait for you to confirm you are unable to reproduce it or maybe that you know about it.

There were no errors after building the lighting other than “overlapping UVs by 0.5%” for example (which is pretty much invisible)

Thanks!
