[Solved] Script issue: Override works fine, but script does not (because script was doing it wrong)

I’d like to put the option to brew single cups back into the tea and coffee machines (this already exists but isn’t enabled), and while it works fine when I override the object tuning, I can’t get it to work when I script it (which I’d prefer, to avoid collisions). Can someone take a second look and maybe spot the error?


Relevant part of the tuning override:

  
    14368
    77667
    ( .. etc etc ..)
  

Script (plus scripthoge injector):

import services

pbox_tea_single_cups_sa_instance_ids = (14368, )
pbox_coffee_single_cups_sa_instance_ids = (13168, )

  else:
    for sa_id in pbox_tea_single_cups_sa_instance_ids:
      attachinteraction(sa_list, affordance_manager, sa_id)
  self._super_affordances = self._super_affordances + tuple(sa_list)

(The long IDs up there are for a custom tea machine that is using the same object tuning as the base game one)

Edited to add: yes, I have scripts enabled -- other (similar) scripts are working fine in parallel to the nonworkingness of this one.
