All is in the subject...
I realized it while playing with the multiplayer mod that I suspected.
I've tested solo with no mods (Only :Harmony, Core, Royalty) and with the debug i gived some royal favor to a pawn.
He was always capable to do all the work.
I tried with every title, no one apply the disallowed work types
They do not care about title food restiction to
I tried with every scenario, it's the same
And a little issues
On the debug action 'Set action menu", "Esquire" titles hasn't be renamed, it should be "Acolyte"
I can verify this.
Title has no effect on worktypes and food.
No effect actually, but they should be.
In the information they said about the food restriction and disallowed work type.
Well, misunderstanding this is only apply to pawn with "Greedy" trait and maybe some another
I'm closing this
