Like most of the jobs, there are certain thresholds that have to be met before they progress to the next stage. In this case, it's the skill/job points associated with the job in particular, which usually has a new progression event every 20 points (up to 80, I believe). So like what was said above, just keep doing the event, accruing the job points, and the next progression event will occur.What's with Mrs. Stranger? I did her chair a few times and now nothing?
Or just cheat and get all the points immediately.
