Whenever I load Bravil Barrowfields before the Lost Spire .esp, I get land tears, but when I place it below, I encounter a CTD whenever start from the main menu. I have the most recent version of UL (compilation) and of Lost Spires.

I've used BOSS to no avail, and so have rearranged many of my UL files.

I'd really appreciate any advice.

Thanks in advance.

Your load order needs to be sorted. If you have a mod that depends on those two plugins, then the order of the dependency should be heeded. Do you have an orange check box in bash when you use the order that causes the crash? Have you been rebuilding the bashed patch after making the changes? If you use TES4LODGen, you should also rerun it after making changes to your LO. Also, remove the OOO respawn week plugin and use the equivalent bashed patch tweak instead. Right-click on the cell respawn tweak and choose the appropriate option.
