To clarify step 4, there should not be anything in the destination folder before you copy the files.

So the correct procedure is to:
4a) rename "Roguebook" to "Roguebook_old",
4b) move "depot_1076201" to the place where "Roguebook" was,
4c) rename "depot_1076201" to "Roguebook".

Fix (to be redone for future game updates):
1) steam://open/console
2) Check manifestID at https://steamdb.info/depot/1076201/
3) download_depot 1076200 1076201 manifestID
4) Copy steamapps\content\app_1076200\depot_1076201 to steamapps\common\Roguebook
5)
