Went to upload my data for the first time in a few months (and subsequent QuestGuru addon updates) and it appears that the latest versions may have broken Quest History?

All I get when uploading data now is

Parsed QuestGuru in 0.08 seconds

There was an error in addon Quest History in method update
Addon Messages:

Quest History

Just to confirm, I'm uploading the SV file from C:\World of Warcraft\WTF\Account\<account name>\Proudmoore\Ransin\SavedVariables\QuestGuru.lua
Interestingly, the addon author has split out the addon history storage across a number of files (QuestGuru_History.lua, QuestGuru_History7.lua, QuestGuru_History8.lua, QuestGuru_History9.lua, etc.) so I assume this change has broken the Quest History Roster addon?

The roster addon currently is not able to handle multiple files.

At the weekend i will install the new version of QuestGuru and take a look what changed and what i can do, to make that roster addon compatible.
