After these manipulations I ended up on a fork out of sync (before I had no problems with stacking/syncing). Few restarts didn't bring any effect.
You don't need to do it, if you have no problems, like I had.
How I fixed it:
1. Close your Breakoutclient
2. Go to ~BreakoutCoin\testnet and make a backup of it
3. Then delete: "database"*full folder, "txleveldb"*full folder, "blk0001.dat"*file, "debug.log"*you will find that it's huge 1GB+ for no reason
4. Now download bootstrap.dat.zip from here
https://github.com/multicurrency/Breakout-Releases/ and unzip it to ~BreakoutCoin\testnet folder
5. You can launch Breakout client now. It may hang, after load, but it's OK, give it time.
Thats it.
Thank you for those instructions!!
Here's what I posted to the slack, which explains what you found:
There is one more bug related to the forking issue I fixed last night. People will fork if they restart their client because I forgot to write some retargeting info to the block index. It gets lost when the client restarts and so retargeting is wrong for the client that restarted and it will start banning peers. I'll have a fix tonight.
In the meantime, if you keep your clients running, the network will hold together until the fix. If you stop your client for any reason, just rename bootstrap.dat.old back to bootstrap.dat and you'll get back on the right chain.
The fix will take care of this.
If you forget to rename bootstrap.dat.old on a restart and ban everyone, just stop, rename bootstrap.dat.old to bootstrap.dat, delete your peers.dat, and start again. You'll get on the right chain.
In the meantime, mining looks good. Expect to start getting Sistercoin blocks in less than 4 hours.
