In retail version.

Shopping list sort button was causing a nil error.

I could make it work by edit line 76 in Source\Shopping\Mixins\List.lua
--table.sort(self.selectedList.items, function(a, b)
table.sort(self.data.items, function(a, b)

The latest alphas already have that fix applied, and I've added the fix into the next release 10.0.44 - available from Curseforge or Wago shortly.
