Oh yes it is more complicated as I now recall. You will need to look at the spells known and all the rest of it. So go through the tabs one at a time and see if anything needs changing. (At times like this we need an explicit Druid v Cleric spell list, which spells are found in each of the two lists?)

The change desired by Tyrion is pretty straightforward, if you were going from Fighter/Thief to Fighter/Mage it would require altering spells known and thieving skills.
