Problem with lighting

Hi everyone,
I'm having a problem with lighting that only seems to appear when I save a particular map as an image (jpg or png) - the problem doesn't appear in CC3 itself, and it only happens with this one specific map. I've tried everything I can think of (which admittedly isn't a whole lot...) but I haven't been able to resolve it.
You can see in the screenshot that the middle third of the map seems to be separated from the top and bottom somehow. I've confirmed that there are no invisible entities in the way, and I've tried hiding different combinations of layers, but no matter what I do the problem's always there.
I've attached the CC3 file itself - I'd really appreciate it if anyone could enlighten me as to what's causing this...
Thanks for taking the time to read this!

This looks like an issue with the Maximum Pixels Per Pass.
If the image resolution is quite large the rendering engine makes more than one pass to render the whole image. There is a percentage overlap but this may not always be enough to capture the source of a light that lies just outside the edge of the current pass. That means the pass may be calculated much darker than it should be.
Type EXPORTSETMPPP and hit the Enter key. In the command line you will probably see the number 4 million. Type 40 million (without any commas) and hit Enter again. Then try to export your map again.
That did it! Thank you so much! I'm not at all familiar with what this command is for - is it documented anywhere?
