First, lets get the errors out of the way, shall we?

The TX pays a 79122 satoshi fee and has a size of 1555 byte. Thats a 50.88 satoshi fee per byte and a very good fee currently, according to your own (@OP) estimate of core as well. Im not sure where the 2mBTC (or 0.2mBTC) come from, but they have nothing to do with the TX linked.
