Alrighty, a new one for today haha. Was just grinding up the last of my Colombian beans to give it a go in the Aeropress, ground about 13 grams and then the burrs just cut out! Had no idea what was going on, had a look inside and lo and behold, a bit of what looks like perspex was caught in the burrs! (Pic below) I have no idea how it got in there... something caught my eye in the bag earlier but I just thought it was the light reflecting off it. I removed it, cleared it out a bit, ground up the rest and still had my coffee, just popped two filters on just to be sure XD. Not sure if the burrs are damaged, they look okay to the eye. And also when brewing, I flipped the Aeropress and gave it a swirl, the top compartment popped off and bit of coffee exploded about and in my face! Looks like today I just wasn't meant to have coffee... XD
