There is a /hqm command to give a player an OP book which will let you edit you current progress .I hazard a guess it is /hqm edit and you need op status but I do not know for sure as I'm at work right now
My thanks, Milord Raetac, for your answer! <reveraunce> Getting the book and what to do with it I already knew (upgraded from 6.5 to 7.4 in single player <shudder>). Getting permissions to USE /hqm edit was the sticking point for me as the server operator. After spelunking deeper into the spiders web than I really wanted to go, I found a place that had a list of console commands. The relevant ones are
OP PlayerName to turn it on, do the happy dance to fix the book, and then
DEOP PlayerName to turn it BACK OFF again!
Most of the Modding community learned this stuff so long ago, they don't even think about it any more. The information is a bit hard to find for us newbies, however. Someday, perhaps, I should collect these things into one place for other new sojourners. Someday...
