Just lost a massive form - crazy output in admin

I had this beautiful multi-page form that I had been working on for a week. I added a custom code element (Some bootstrap - see below), and after the save - the form was, just, gone. Below is a snippit of the code that now displays on my CF5 admin when selecting the form:
[code]<"m-signatur<-pad">labell<s][fields]"m-signatur<-pad--body">labelll<canvas width="<?php echoi$rm-gr>rm-g["w" i"]["="form"]["ow-For"][xtras"width"]; ?>"mheight="<?php echoi$rm-gr>rm-g["w" i"]["="form"]["ow-For"][xtras"height"]; ?>">< canvas>labell<> n vaon="clear"><?php echoi$rm-gr>rm-g["w" i"]["="form"]["ow-For"][xtras"clear_Npar"]; ?>< button>labell<> ama_path4rmextram>

Here is the code that I was adding (benign):

<div class="jumbotron well">
				<h1>
					Hello, world!
				</h1>
				<p>
					This is a template for a simple marketing or informational website. It includes a large callout called the hero unit and three supporting pieces of content. Use it as a starting point to create something more unique.
				</p>
				<p>
					<a class="btn btn-primary btn-large" href="#">Learn more</a>
				</p>
			</div>

I have absolutely NO IDEA what caused it, but thought you guys should see the aftermath. I have started anew, and the custom container worked just fine on the next run. Only thing I can figure is DB lag.....

I do have a backup for the DB from last night, but don't see the form anywhere...any hope of just losing the last 3 hours of work?

Found it - backup restored.
