Forest Mesh not saving, thought that was addressed.

Made a few trees, new mesh brushes. Come back later and they gone like the wind.
Someone else told me a while back about this happening.
Its not a big deal, I been hand planting stuff a while anyways, but would be nice to use it sometimes. Guess the data block is not being saved, the new brushes are there, but the forest item mesh is gone.

 

Sorry, replying late, I made a quick video. (1) Forest Item Vanishing After Summer 2021 update - On my system/level - YouTube

Not sure if this matters, but anything drawn with a custom forest mesh this pops up
I can load my own mesh into an existing forest mesh and it does save what I paint
I can just use some of the existing meshes for the time being. Its not like I have a lot of stuff to use the forest tool with. Just seems to be a problem with the new creation of a mesh object being saved. Which I remember that button being fixed in a recent update.

 

I have the same problem but I find a way to add new items. it seems like the new version doesn't save the managedItemData.cs file (art/forest path) so I add my forest item manually and now it shows on the map
I also manage to restore some of my work (2 hours I think wasted ) editing back the *.forest4.json.for.bak by removing the .for.bak
