Just Like the Good Ol' Days: Dupe completely ignoring pri-9 outhouse job and messing everywhere instead!

@Kauffy, you have two issues with how you've set your priorities:

1) All of your mealwood planter boxes are also set to 8; so the duplicants prioritize them over the outhouse. The problem here is that the farming errands have a hidden priority of 0.28 priority vs the tidying hidden priority of 0.26. The hidden priorities can be seen when hovering your mouse over the errand in the duplicant's "To Do" list.

2) You have set a non-Tidying errand type to high for for all of your duplicants. Meaning they will prioritize building (Bilderberg), Researching (Sciencio), and Digging (Diggby) over all other tasks - even if those tasks are set to 9; they will always do what their highest duplicant priority is.

As the game describes "Duplicants will first choose what Errand Type to perform using their Duplicant Priorities [L]. They will then choose one Errand type from within that type using the Building Priorities set by [the Priority] tool."

Just remember, the "To Do" List is super helpful in determining what your duplicants should be doing next - like making sure mess-apocalypse doesn't happen.

Hope this helps!
