I saved https://www.reddit.com/r/TestPackPleaseIgnore/comments/3ieifr/aaronhowser1s_hqm_pack/ into json format, and did some edits (Just switching out items). When trying to /hqm load all i get the above error.

For the love of god, use pastebin to post logs. Also, I would need your complete log, this doesn't say much.

Also, single or multi player?

Also, did you remove the quests before loading? It won't allow you to load already existing quest sets...

Ah it was the fact that the quests were already loaded in book. I thought it would update with the changes to the quests. Sorry!
