Not sure which piece of the UI is causing issues (maybe DASH since I was also getting an error on there while ProcsHUD was running), but since the updates last night, I have had to disable ProcsHUD for constantly erroring. ProcsHUD hasn't changed, only pieces of this UI. Not a huge deal for me, I don't need it, but just a heads up.

...Roaming\NCSOFT\WildStar\Addons\ProcsHUD\ProcsHUD.lua:715: bad argument #1 to 'pairs' (table expected, got nil)
stack trace:
[C]: in function 'pairs'
...Roaming\NCSOFT\WildStar\Addons\ProcsHUD\ProcsHUD.lua:715: in function 'HideAllProcWindows'
...Roaming\NCSOFT\WildStar\Addons\ProcsHUD\ProcsHUD.lua:693: in function <...Roaming\NCSOFT\WildStar\Addons\ProcsHUD\ProcsHUD.lua:679>

I didn't get the Dash error before it went away, and I can't seem to replicate it now.
