au bout d'un moment le fermier se bloque dans le champ et il ne bouge plus, il faut le faire respawn a son atelier pour qu'il se remette à travailler

The citizens have issues with slabs and similar above water. (there are other issues for this) which cause this.

j'ai changer le texte du probleme car il avais un bug que j'avais oublier de dire

Sorry, I don't speak french, what's the issue?

At some point the farmer is getting stuck in the field and doesn't move anymore. One has to respawn him to its farmer block (I guess he meant recall) to make him go back to work
