Good job dev, seem to have fixed the chain
However it seems to be issues with found blocks
http://egano.cryptonight.me/#pool_blocksFrom daemon:
2018-Jan-18 20:47:52.032865 WARNING Transaction b1f9ed39f37cce35871414092572ad4c593f849621ed87ca11c0f5986568b42b is not valid. Reason: Transaction uses spent key image
2018-Jan-18 20:47:52.032927 INFO [185.34.216.108:47767 OUT] Tx verification failed
Chain seems fixed indeed and both version 1.1 and 1.2 of daemon now can sync, 28 blocks mined earlier around 29056-29084 became orphaned. Anyone who sent transactions yesterday should reset their wallet in the way MrCross did few posts above.
Don't worry of the invalid tx, it will be rejected until it completely disappears by expiring from the last mempool.
We are now above 31000. Thanks everyone for mining!
