Mandatory upgrade:
https://github.com/title-network/title-network/releases/tag/v0.17.0.5There was an exploit of version 0x21 blocks where for 6 days 1-3 entities mimicked ASICs and got a handicap mining.
At block 915000 the bug fix was activated by v0.17.0.3. The exploiters left the network at too high a difficulty, therefore we needed to put in a 34 block grace at 53k difficulty in v0.17.0.5.
Seamless upgrade from v0.17.0.3 to v0.17.0.5 as the datadir only contains locks that match consensus.
Those who were running v0.17.0.2 into the split in network may have issues syncing because of the greater perceived work done by the 0x21 version block exploiters.
The solution is to go into Help -> Debug Window and locate your datadir path. Shutdown the v0.17.0.2 wallet. Go into your datadir a rename the last rev*.dat file to whatever you want.
Then proceed to install and run v0.17.0.5. It may take a long time to open your wallet as it re-indexes. Please be patient.
On Mac and Linux you can open a terminal window and tail debug.log in your datadir to follow the progress until you reach the same chaintip as the explorers
