The WorkTypeDefs MUST be one of the defs in the WorkType folder.
As there isn't a def named ManualSkilled it is not a surprise you get that error.
Try Cleaning or something else from there instead.

I cant get this to work. So far I've tried putting compatibility thing it and the end of the Misc, and and the end of my mod load order and It results in a screen either covered in dirt or with nothing but rocks. No pawns, no animals, no trees.
Sorry but can you tell me what you want to do?
The patches are only for when you have the other mods also active. THEN the patch needs to be loaded LAST.
Which patch do you want to add? Only the Prepare Carefully patch, then load Prepare Carefully, then the Miscellaneous stuff and then the Patch as the last one. Then it should work..
