Obviously that's not a fix, as it removes any of the modifications made to that module - based off the changed data for that module it appears to be changes to some images that make up the bulk of the data saved.
Investigating further, if I revert changes on only "The-Plunging-Torrents-Player" map, that reduces the save time to what I'd expect (0.2 seconds).
Thanks for providing the test campaign. Hopefully this will help the devs investigate further as we know it's an issue with one specific changed image in a module.
