I have a notepad widget in my sidebar. In it I had used sCode to make some links to places on site I want to visit, such as the bath house. For some reason when I clicked the link that should go to the bath house, the code I wrote in the notepad widget changed. Now the URL for the bath house I had input is replaced with the URL for a broken zendesk support article written for an MMO (coincidentally, an MMO that I was playing as this bug occurred). Every time I click the link it takes me there because it was a permanent change.

It's not like I was editing the code and somehow pasted in a URL I had in my clipboard... It was just a single click to get to the bath house. I've never even visited the page that my notepad links to now. Sorry I don't know more. It's no hassle for me to change it back, but such a weird bug.

Chrome Version 71.0.3578.80 (Official Build) (64-bit)

It hasn't happened again since.
