Bitcoin Core 0.12.0 forces me to pay a certain fee.

I feel like a very dumb person right now. I saved the raw transaction form with the address : 1TtxVxWQwXCcdrbzXFQZGnrBP8oSVjYwP that I used previously. And today I wanted to send 0.0348 to my exchange account, but I forgot to change the receiver address, and now I lost these coins for ever as I deleted that wallet file. I am glad I made this mistake with a small amount right now, and not later with a large amount. I know what I did wrong now.

I removed the address from the form and changed it to "INSERT RECEIVE ADDRESS HERE''. If I again forget to add the right receiving address, it won't send the coins to the wrong address anymore.

I presume you don't have an old backup somewhere?

That's correct. I usually do make backups of all new created wallet files, but not in this case as it was supposed to be used only once.
