Saving the map does not save voxel data

[bblpny]

Hey phy, so if you load up the editor and a level with a voxel world in it then steps below:

• paint some voxel changes
• press the save all button
  It saves the level and marks the changes to voxels save asset as needing to be saved. So you have to press save all again, to actually have those voxel changes save to disk. We're still on an old version of the plug in but this seems to be the cause of the data loss.

ctr + s doesn't save voxeldata
just marks it to be saved.
ctr + S multiple times will never save voxeldata. But you will get a prompt to save voxeldata if you ctr + S then close the program.
Closing the program without ctr + S or at least 1 save all  will never save voxeldata. 
Save all once will never save voxel data. Save all twice however will.
Oh, and autosave marks voxeldata to be save when closing the project though it doesn't save the asset itself
