Yepyep. I think for those that do not know what is going on the job change could be hard. I read the wiki before doing mine for all 4 of my classes and they were easy to me. However, someone who does not have the heads up and does not know what to expect, may have some trouble with it. Especially the younger kids that are playing.
And @ Loki, yepyep, no mater how much testing, planning, and double-checking, issues always arise, not just in thris game but everywhere, that is why they came up with Murphy's Law.
