I was sending some coins from my daemon to another wallet I pasted the address e.g D12345456789 but the funds did not reach destination so I checked lastest transactions and found that the coins went to a different address e.g D89899999090
hmm
looks like some kind of a malware...
If you are sure you type a correct Dogecoin public key and it was changed during transaction - it looks like some kind of malware on your computer. But it might be due to some wallet bug ....
Check your computer, download: spybot search&destroy , AVG antivirus (even free version is very good) , CCleaner ...
