Lost some coins, maybe someone could help me...

Hello,

About 3 days ago I lost 208 deviant coins worth about 300$ at the current price and can not figure out what happened so maybe someone here could help me. I had around 370 coins in my wallet that were staking since Devian coins are POS. I hade some urgent bills to pay so I decided to sell some and here the problem begins.

I want to send some coins to the exchange but as soon as I pressed send the wallet crashed it was a runtime error or something. I backup my wallet and try it on 2 different computers but the problem was the same it crashed the wallet. I ask the devs but they said that only I have the problems like this and most of the time they were just ignoring me. Since I did not want to lose this money I was thinking there is a probable problem with the broken wallet.dat file that I tried on different computers and crashed the wallet. So I exported my private key from the wallet. and download a fresh and latest wallet. I imported the private key but I had only 209 of my 370 coins in the wallet. I said ok let's see if I could at least send some coin out so I sent 1 coin to the exchange and it was successful but still 170 coins are missing so I put my old wallet.dat file back and here the strange thing happened. All coins were there but I saw a strange transaction was made to an unknown address with 208 coins, this is the amount that was in the wallet when I input my private key. I closed the wallet and open again and the 208 coins were missing.

The transaction was made at the exact same time when I send 1 coin for test and what I don't understand how was it possible to send coins in the same transaction. I just can't figure it out what happened. I don't think I was hacked since the coins are still at that address. I don't understand how can I send coins to 2 addresses at the same time on 1 transaction. I cant find the transaction on deviant block explorer it was there yesterday but I can't find it today.

Does the wallet automatically creates a new address and send coins there if you input your private key?

Transaction ID: 697425819925a6ce152eefd9acefcc87a6e24e2d457c02ad3fa3417015ffd86f-001

I know that the coins are probably lost but I just want to know where I made a mistake.

Thank you all for your help...
