So, after fixing the faction gain from escort missions, i think something may have stopped working. After a certain point of trade missions at +999 faction, I stop recieving the "XXX faction increased" messages.

Note: I continued to recieve messages once I had hit +999 faction, but it was after doing 4 or 5 more five-jump bulk procurement missions, I stopped recieving the notification that my standing had been increased. Is it now impossible to get POS faction? I spoke to players who had obtained POS standing pre-escort mission bug, they told me that at no point did they stop recieving "XXX faction increased" messages.
