The villagers have stopped collecting wood!

I dont know what to do, they just dont collect wood anymore. There is a worker available, but they dont collect, I have zero woods and boards and I dont know what to do now.

making a work camp always fixes that bug for me (as in not just work camp collects wood but laborers also resume collecting wood). also check to make sure there are more trees selected for harvest and that they have not finished the task list you gave them
