Minion wants to update to older versions of what I have installed.
I am running Minion v3.0.5 on Windows 7 64bit. And for some reason Minion wants to update addons to an older version to what I have installed, or a different number altogether. Granted I use Curse as well as some addons get updated there first.
If you update some addons from Curse, and the addons' authors keep them more up to date at Curse, simply right-click that addon in Minion and set it to ignore.
