nope

Okay so I haven't tried that with this mod but it has worked for some mods in the past so maybe it'll work for you too. Backup your save first. It can be found in C:\Users\%username% \AppData\LocalLow\Ludeon Studios\RimWorld\saves

Delete every single thing associated to pawnmorpher via the dev mode (destroy button), including all mutations from pawns (Remove hediff button), former humans (also destroy), items and whatnot. Use this mod to remove the morphs faction (read the description too because it has hotkeys to different editor menus including faction editor):

See if it works, if the save loads, if pawns can find path normally, if your screen isn't gray, if all factions didn't suddenly disappear off the whole world map, if your UI is still there, if your console is not being spammed with infinite errors (you can try saving and reloading and see if it will fix it) and if the desyncs are gone (or perhaps if they are worse lol).
If any of those issues happen (or ones I did not cover here) revert back to your backup save.

Thanks! will give it a shot
