@N-R-K which room (if it's public)?

On a certain room scrolling up a bit makes cinny black out entirely.

Hmm, my wording was bad here. It's not scolling up itself that causes it, but rather scrolling up to a certain msg. Not sure which one, since everything goes blank.

This was the message causing this:

<a href=https://yewtu.be/watch?v=wl-LeTFM8zo>HOW IT FEELS TO CHEW FIVE GUM GUM GUM YOUR STIMULATION<a/>

Whoever sent it, wrote closing tag wrong <a/> which is causing blackout.

Ahh, I see. Thanks for looking into this and fixing the bug.
