Someone else give this a try

Eliminate the duplicates on this list. I've tried about 5 times and I keep getting a 504 Gateway Timeout.

I get "0 duplicates found and removed". Maybe someone (very quickly) got to it before me, or one of your attempts actually did go through...?

Okay, that's weird....because a couple seconds ago suddenly on my screen (while I was editing a different list) the message appeared "43 duplicates removed." I think that was for the Best Ever list, because there's no way the list I was editing had 43 duplicates on it. So I guess my tries went through on a delay.

I have been getting the Bad Gateway message a lot when editing or combining also, but a little later the edits have been made when I checked back.

I think the system is just getting slower and slower. Presently, it will screech to a halt.
