I tried to run the Simulationcraft addon, and I keep getting this error: Message: Interface/AddOns/Simulationcraft/core.lua:369: Talent loadout ‘pvp’ is corrupt/incomplete. Find that talent loadout in your talents UI and delete or update it. It may be on a different spec.
Then dump the data from the saved variables folder for this addon, or edit the line mentioned in the LUA error (369) in the text editor of your choice. That’s doable without removing and re-installing the addon.
