Does anyone know how to fix Landmass plugin loading all world partition cells that exist?

A colleague told me:

"If you enable the Landmass plugin (or use the built-in Water system, which relies on Landmass brushes and Landscape Edit Layers under the hood), it regularly breaks World Partition’s ability to unload cells in the editor"

Apparently... it does. so if you're working on a project the size of project titan, it will load THE ENTIRE MAP, and calculate ALL OF IT. I'm sure there has to be a workaround for it?
