Not while here, no I haven't. I was cheated/almost cheated about a week back though on Reddit. I was going to buy a Marshal that was said to be almost 100% original for about 10m. She wanted 20mil for him originally but since he wasn't 100% original she said she'd take 10mil for him.
The girl said she almost never talked to Marshal and that he should be almost original. I went to her town and dropped the 10mil bells as quickly as I could, then grabbed Marshal and told her to end the session. She instead of ending the session she "flipped" the switch. She came back on Reddit and said "I'm soooo sorry, you did all that work and now it's all gone. Do you want to just come and grab Marshal for free?! I don't need the bells"
I was also in a rush because Fang was waiting for me, so I told her to hold Marshal for me for a few hours and I'd come back and do it all again. She still offered him for free so I just went and grabbed him. I ofcourse didn't feel right about just getting Marshal for free so I grabbed a bag full of bells, about 1.5m and dropped it as a form of "tip".
After it was all said and done, Marshal moved in and it turns out she lied. Marshal was not original AT ALL. ALL of his furniture was gone, even the sloppy table. I was furious, but I got him for 1.5m so I can't complain. Just to think that the girl wanted 20mil for a 0% original villager got my blood pumping, so I'm now sooo glad that whole ordeal happened though. ^.^ I'm currently working on restoring Marshal's house to its former glory.
