After 4984 block, released 1.1.1.3 version and added two mining algorithms and replaced difficulty retarget for this, if you mine with oldest 1.1.1.2 - you mine on forked chain, i warned of this before update release...
Is that means lose all coins after each updates? I was mining at latest wallet in that time, and after update all coins are lose, usually after fork coins save at address but there is not worked, very very weird system
Again, you lost coins only because of your inattention, how many coins do you have?
I haven`t problems with attention, get last version from this thread and github on that time, I can understand if I lost the part of coins that I mined after fork, but lose all, that`s look very strange. I mined about 1300 coins.
You use dumpprivkey\importprivkey?
When you mine new block in solo, reward added to reserved wallet addresses, not to your address, if you delete wallet without send all mined coins to your address, you will lose them.
Something like this happened. When upgrading to new version of wallet, you do not need delete wallet.dat!
In order to avoid the recurrence of this situation, use dumpwallet \ importwallet command or send all mined coins to one address after mining.
Give your wallet address, i will compensate for your loss.
I know about all coins to one address, but I can`t to do that bcs wallet was offline after release new version, I dumped current wallet.dat and then update wallet and after that stack drop to zero and importwallet or importprivkey don`t work.
