Need to investigate where this is coming from.

Nearby sorting is using numpy for speed, we should either use numpy for all sorting stuff or convert nearby sort to normal list. I'm currently reworking sorting so it's probably best to revisit this after the sorting changes are done.
(my PR will set default sorting orders for each menu item, and probably allow the user to override them in the settings)
