Hello,
need an advice, this is the 2nd day when im trying to figure out such a bizare problem, the point is when im trying to open simcraft output on my prot paladin its not working, but when i switch to a diferent spec on same char it works normaly, i tried to disable all addons expect simcraft, tried to reinstall it, deleted variables, checked game data for repair, tried to unequiped gear slots, nothing. Any clue what to do? I will apreciate your help.

Resolved by Trips in paladin discord, need to manually activate every single Protection build saved to load a new tree, than it worked fine. I'm closing as resolved.

I think it's a Blizzard bug. I've made an adjustment to the SimC addon that might fix it or might just change the kind of error. Will keep an eye on things.
