why would my nats code change?

[A Priest]

added a load of galls from sterling cash into a tgp script of mine about 1 month ago, then today i go to collect the new batch and yet when i add them in it doesnt detect any duplicates, reason being that my nats code has ever so slightly changed eg:

before: http://galleries.sterlingcash.com/nats_ibwf/pink_creamy/?nats=MjAzOToyOjI,0,0,0,

after:
http://galleries.sterlingcash.com/nats_ibwf/pink_creamy/?nats=MjAzOTo2OjI,0,0,0,

any ideas? its just messed up my script nicely any way as I now have 60 duplicates to manually delete.:llama:

I'll field this one ;)

The first link you refer to is for our 60% revshare program, which until recently was the default one. The second link is for the 50% console-free option, which is now the default. So each batch of links are using a different program, one at 50% and the other at 60%.

Hope that explains it - please contact me if you need anything else.
