Spacefarer Module Issue

One of the Spacefarer Modules in the attached save file is causing performance issues. Deconstructing it makes the game freeze for a minute or two. After the game recovers from the freeze the frame rate becomes almost double of what it was before deconstruction.

Before deconstructing this rocket I've deconstructed 6 or 7 almost identical ones with no freezes and no significant increase in frame rate.

I've also tried to deconstruct this particular module on my older save, which still contained other rockets and bases on all planetoids, but the game froze for 2 hours and crashed shortly after recovering from the freeze. The frame rate was also almost doubled after the freeze.

Edit: I've made another attempt to deconstruct the problematic module on my old save. The game resumed after freezing for a couple of minutes and I was able to save it. After loading the game was running twice as fast, also after rebuilding and repopulating the deconstructed module.
