0.24999772 BTC went to some random address that I don't know of.

WTF is this shit? Did I just get robbed or what?
Thats your change. You used a 1 BTC bill to pay 0.75 BTC to your friend and 228 Satoshi to the miners. Your change is thus 1-0.75-0.00000228 = 0.24999772 BTC
You can see the address is part of your wallet if you enable coin control (Settings -> Options -> Wallet) and go to Send -> Inputs -> List mode
Weird, I never knew about this.
Thanks for explaining it to me.
But why would the TX fee have changed?
I've never touched it? I've done hundreds of transactions without anything like this ever happening.......
Times change. Try using .0005 fee for all transactions.
This is way too much. 0.0001 will do in most of the cases, 0.0002 when there are maybe some stress tests, etc. I am sending always like this and not once did I have any problems.
