I decided to try and break the new job changing system, and discovered a fun little bug:
- Pause the game.
- Promote all your workers to the same profession (eg trapper or carpenter, with just 1 talisman available).
- When the first one is promoted, tell him/her to become a worker again.
- Watch as another one of the workers you ordered to promote to that class runs over to pick up the talisman. They will abandon other tasks to do this (at least, harvesting ones they’ll abandon).
Whilst fun, I’m thinking that this is, or should be, unintended behaviour: your workers should stop trying to promote to carpenter once you’ve got one, etc. At the very least it sounds like some unnecessary orders clogging the job queue for each worker.
