[PvK]

No, the patch doesn't touch Proportions. Proportions files aren't affected, and when using the mod, the mod's data files are used instead of the game's patched data files.

Meanwhile, all the hard-coded changes (AI, interface, bug fixes, etc.) work fine, and I don't know of anything but improvement when using Proportions.

Sometimes you do need to make a fresh install of SE4 before the finicky installer will run. Other times, you don't. If you do, you can then copy your old Proportions files into the new SE4 install, and it'll work fine (assuming the copy goes right).

The main issue with mods and the new patch is that mods don't get changed by the patch, and a few of the mod changes are in the data files which mods need to include. This is why I made a new Version of PvK Balance mod - because it doesn't change the data, so if you use Version 1.0 of PvK Balance with SE4 1.91, a few of the the SE4 1.91 changes get set back to 1.84 status - like the population curve, and component and facility tweaks.
