I'm an idiot and I knocked over a full mug of tea all over my mouse, mousemat and a large nest of wires and extension leads under my desk. Idk how, but it shorted out every electrical device in the house. Neat!

My mouse still works, but it was all crackling worryingly and full of tea, so I'm just gonna go ahead and get a replacement...

On the bright side, none got on my tablet! :D
