Strange behavior with list - it disappears and chrome plugin fail

Two problems in one report - not sure if they’re associated so I’m posting them together

i made a new long list - spent a while editing it in safari… here’s the list:

notice if you go there that it exhibits this behavior of appearing and then disappearing - I recorded a video:

It started happening after I added the Listly plugin in Chrome and tried to use it (see also the video as I do a demo of the problem there).

The disappearing list did not happen until after I installed the chrome plugin and tried to add something to my list.

I’ve tried in safari, chrome and now opera, (viewing the list) and all 3 show the same symptoms.

Exact same issue. Also affecting embedded lists: http://www.beststartupresources.com/legal/

It looks like it is sitewide. Checked a few other lists.

A new release about 8PM PST (May 17th) broke something unexpectedly. It has since been rolled back and everything should be working again. Apologies!

Thanks! Rolling back fixed both problems I reported
