After hearing about the hard fork and upgrading to 13.1 via git pull, my litecoin p2pool instance has been showing insanely high share difficulties of around 16 days expected time per share (pool rate reads around 700 MH/s). So I haven't gotten any LTC shares or payouts since July 4. I thought maybe this had to do with the fork before most clients have upgraded, but the difficulty has not noticeably decreased at all in the last couple of weeks. Meanwhile, my BTC p2pool instance behaves normally. Ideas what's going on here?
