Missing Post

I don't know where else to report this, but for some reason, I can't find my post that I had referred to in another post. The post was originally addressed at:

#RestoreCANVAS

But when you click on it, the page opens up, and my post is missing. And it is an important post, too, with actual advice on how to make front-end code for my "Classic View" mode of the WebGL low-res renderer. I was giving the developers free use of the code I had modified, and I have no problem letting them take it for their purposes. But it's just gone, now.

Did it get hidden or deleted somehow? Did the developers at least get a copy, first? I only wrote the code in the message post system, so I don't actually have any copies, and it'd be annoying to have to recreate it, since it was already done well.
