Issue description
In all fairness, I assume that this is something that you probably already know about. It seems harmless enough but I'm just not a fan of leaving errors live comfortable and neglected lives. They all need to be squashed (or at least reported lol).
There really isn't anything that I can tell you about specifics because it has been happening now for as long as I can remember and it duplicates itself, so it's in the log twice. Same error, same instance, double reported. In all honesty, it looks like it's probably a Unity specific error that we might just have to live with. It happens no matter what and under no special circumstances. It doesn't crash the editor or anything sooo...
But yeah, anyway, it's this:

I'm mostly just sending this in because I don't want to publish the map when I finally get it done and potentially have it crash out when people try to play it, but thankfully, if I'm correct, I don't think it's harmful in that sense.
Reproduction steps
Most times when I load or save my map in the editor is when this happens, or after an autosave too. Never during any actions while editing, that I've noticed. My guess would be that it's just maybe that the editor still has some rough edges with polygon features (which is all of the features basically lol there's ALOT of polygons everywhere...for everything... haha...which is why it's such a funny and unhelpful error message for it to throw) and how it stores the preview images.
It might be occurring when it fails to generate/encode the image data for one of the terrain regions during the undo snapshot (wouldn't be any of the other asset types)...since another thing I've noticed is that sometimes undo either doesn't work or skips the most recent action and undoes something else instead. So now I just don't make mistakes that would require an undo, so that's a silver-lining.

Attachments
Sorry, I don't really want to give my map out in public but I'm sure you understand. I could email it if you really wanted to take a look if this seems unusual after all? Shoot me a msg to callaaron (-a-t-) proton (-d-o-t-) me, if so. (added those dashes cuz bots know the brackets avoidance trick these days)
