Did you try running the game in admin mode (Note: You have to start a new game). See if this fixes your problem.

Not yet. Is the admin fix one-off (that is, run in admin mode once as a post-install step, fix forever) or do I need to always run as admin?

I haven't had to run the game as admin for any of the previous builds, this is the first time this problem appeared. I'd rather not run as admin all the time, so if the workaround isn't permanent it should really be fixed.

Ran into this with forests with .99. Ran as Admin once and obviously it didn't fix it. Not seeing swaps/forests sure makes knowing how long travel takes rather difficult!

Alas, I doubt I would be a good test of the installer changes since I already launched in admin mode, which did correct the problem for me after starting a new game (although I had to delete all my custom sovereigns after they lost their heads).
