Hello everyone, realise some time has passed on this, but I'm trying to find others who are stuck and can't unlock "Payday", if you are one, read on...
As well as renewing my cause for a patch for the "other" console, I shall also be pushing for a second PS3 patch to correct the issue for those who were caught in the Payday pre-patch requirements issue.
If you don't know what that is, those who played Ranked Campaigns like troopers before the patch, met the requirements for Payday on each of the 4 campaigns (be sure to check the requirements, these are quite indepth and plenty of opportunity for a campaign you play NOT to count), hence they met the requirements for Payday and should have been awarded it, but weren't because this and "No Job Too Big" where glitched.
The patch was (eventually) released on 26th August 2009, and players where able to find and capture Polar and Glutton Slimer for "No Job Too Big" and completing the 4 campaigns (to the payday standard, published in many threads on this very forum) unlocked "Payday".
Except... Payday didn't unlock for all, it didn't unlock for those who had met the requirements for it before the patch, as hard as they tried, it wouldn't unlock.
Knowing a bit about code myself, the answer is obvious, each time you complete a campaign to payday standard, the game records a "flag", a marker, a small record that campaign has been done to Payday standard, but ONLY if it hasn't been done before, no sense setting a flag to yes that's already set to yes, right? Upon setting that flag, it then also does a check "Have the other 3 campaigns been done?" If yes, award Trophy, done. If no, do nothing. Both options end in the continuation of the game. The important thing to note is the game only checks and awards the trophy IF you've not already done the campaign to Payday standard.
Therefore, as long as there is just one of the 4 campaigns not been recorded as "done to payday standard", if you then do that campaign to Payday standard post-patch, you get Payday. Unfortunately for those who have done all 4 campaigns to payday standard, the game doesn't re-evaluate and award it.
I shall be pushing for a new PS3 patch to correct this issue for those affected while pushing for a patch on the "other" console for the same two achievements (but hopefully without the Payday glitch still present in the PS3 patch for some).
If you are one of those affected and have a facebook account, please join this group and support the cause, thank you.
