you sure that those addresses are not your newly generated
change addresses? some people got fooled by that.
there's a high chance it could be because my transactions took more than 5 days to complete. how am I able to get it back from the newly changed address? I'm using bitcoin qt
If you are still using bitcoin qt you should update to bitcoin core, maybe you just stuck to the old name though. Latest version is 0.11.2, 0.10.3 is fine as well.
To see your change address you have to change some settings that are not available in the old versions. You have to enable coin control. To do so:
Settings -> Options -> Wallet -> check "Enable coin control features"
once you did this confirm with ok. It might have to restart, Im not sure. Once you are back on the main screen do:
Send -> Inputs -> select Tree mode and search for the addresses you know, e.g. 1KsvvEnFofFHogEWQMn4Kg3ZsisTxChonr for this[1] TX. If you click on the small triangle to the left you will see another address labeled as "(change)".
