My notes on every one of my trades have been getting "cached" to out-dated ones, returning my prices for items I'm buying to the wrong prices. For example, I could be buying a Strange for 1.44, but the old prices was 2 ref, and EVERY 12 hours, my notes get cached back to 2 ref. It's annoying, as people keep sending me trade offers for THAT price, as I can't notice my prices got cached. I haven't been bumping my trades too much, too. People just end up seeing my old price and go "Oh this is an awesome price" when they're really seeing an outdated price.

TL;DR: Please, please please fix the whole glitch that makes notes get reversed to past notes.
