If you are good at resolving issues yourself it's not bad doing an LP on the pack. I am doing one and between updates I backup everything and download the update, try and open the world up and check the HQM book first. Usually this is where oddities arise and you have to use the /hqm edit book to fix things and trash the extra rewards. Overall updates aren't bad and rarely you have to do some odd things like the .5.0 to .5.1 update and deleting the HQM data because I believe some ID's were removed from the world between updates.
