Ah it was there earlier, I had to restart the pool to detach devcoin merging, and I think it must have wiped the two blocks p2pool found from local memory, so they're not on the local list any more - they'd still be on the p2pool network.

EDIT: hmm just had a look myself, couldn't find it...hmm...I wonder if it got bumped.

EDIT: If the payment doesn't arrive and you should have received it, worry not, I'll cover it until I know the server's working properly (and I get the devcoind thing sorted out)
