I have the same problem with missing inputs, I did the tx from bitcoin core with custom pricing 71 satoshi/byte but tx cannot be found on blockchain. Blockchain still has the record of the btc i mined and my previous transfer but not the latest one. And my Bitcoin Core wallet shows 0 BTC now.

Status: 0/unconfirmed, in memory pool

It has been 2 days, obviously there is a problem with the tx inputs. I get the same msg from broadcaster. tried zapwallettxes and rescan after . Should I try the abandon transaction ?
Any help appreciated , sorry to highjack your post.
