[2.0.23] Crash deconstructing asteroid collector (AsteroidCollectorNavmesh: unregistering chunk not forced in navmesh)

[foooey]

On my "Aquilo Runner" platform deconstructing the final asteroid accumulator on the top of the platform triggers a crash to desktop

The specific accumulator doesn't seem to matter, only that it's the last one along the top edge. I can add and remove accumulators, but any time I remove the last one it crashes.

The attached save file reproduces the crash. It has all other surfaces deleted via `/editor` to make it smaller, but I can provide the 38mb full file if needed

Asteroid collectors have been changed recently, can you reproduce this in the experimental (2.0.26 or later?)

I switched to the Latest 2.0 Experimental (2.0.27) and I am no longer getting the crash on any of my save files

Thank you for your help. I'll stick around out here in bleeding edge land for a while.
