My suggestion would be to update the core, bitcoin v0.10 solved the POW drifting problem; peercoin has also new fixes that make help.
It appears that pos and pow are both working again.
Also - Wallets can not have POS on while syncing, this can cause forks!!! Please hard code POS off in the wallet until synced.
I am 100% supporter of MAGI, I run a full node to support the network, currently have 53 connects.
Keep up the great work, you are one of few that are truly honest with the community.
