The recent versions of OCTGN introduced a serious bug which significantly affects the way ANR works. More specifically, it is bringing player decks in an out-of-sync state between players after shuffling.
This means that as a runner, your R&D accesses will not view the top cards of the opponent’s deck as the corp sees them and you will instead be seeing the deck as it was pre-shuffle! Other cards like Indexing will also appear broken.
There is nothing I can do about this at the moment as it’s an engine bug and it affects every pile manipulation via scripts.
I’ve informed the developers and will inform you on the blog and the MOTD when there’s any news.
Until then, playing ANR will probably be impossible as all your R&D accesses will be false.
